www.phocos.com 2 | Page 1.0 Introduction Dear customer, thank you for choosing this quality Phocos product. The Any-Grid™ PSW-B pure sine wave battery inverter / charger series has numerous outstanding features and use-cases such as:  Function as purely Off-Grid inverter for applications with no AC power source  Function as solar enabled (optional) uninterruptible power supply (UPS) functionality for intermittent or unstable AC sources  Function as grid-connected or AC-generator-connected inverter to reduce energy demand from the AC source by prioritizing solar and / or battery power, thus saving energy costs  Integrated MPPT solar charge controller means no external charge controller is required  Battery charging from an AC source such as the public power grid or a genset  Compatibility with multiple battery types including lead-acid (gel, AGM and liquid electrolyte) and lithium-based batteries such as LiFePO4 (as no battery management system communication is possible, ensure the battery can function without external communication before use)  Both neutral (N) and live (L) wires of the AC input are automatically disconnected (break-before-make relays) from the AC output when the Any-Grid PSW-B operates in Off-Grid mode  Grid feed-in is technically not possible as this device is not grid-interactive. It never operates in parallel to the AC source. It either uses the AC source to power loads directly from it (the inverter is not running at this time, the unit is acting purely as a load) in Grid mode. Or, in Off-Grid mode, the integrated inverter module is running, but isolated from the AC source on both neutral (N) and live (L) wires through air gaps.  All-in-one unit allows simple and fast installation, and easy configuration  Optional accessory: Phocos Any-Bridge™ IoT Gateway (sold separately) to connect to the PhocosLink Cloud from anywhere with any internet-capable device via its web browser This manual describes the assembly, installation, operation, maintenance and troubleshooting of this unit. 2.0 Important Safety Information SAVE THESE INSTRUCTIONS: This manual contains important instructions for model PSW-B-5KW-230/48V that shall be followed during installation and maintenance of the unit. Read and save this manual for future reference. WARNING: The installation of this unit may only be undertaken by qualified personnel with appropriate training. High voltages in and around the unit can cause serious injury or death. This unit must be installed in accordance with rules and regulations at the site of installation. CAUTION: A battery can present a risk of electrical shock, burning from high short-circuit current, fire or explosion from vented gasses. Observe proper precautions. WARNING: This unit must be connected to a permanent grounded wiring system. Be sure to comply with local requirements and regulations when installing this unit. BATTERY TYPE: Suitable for use with lead-acid (gel, AGM and liquid electrolyte) and lithium-based batteries such as LiFePO4. OVERCURRENT PROTECTION FOR BATTERY: Install an overcurrent protection device with a minimum of 1000A interrupt rating as close as possible to the battery terminal. Select a device rated for 1.25 times the nominal current rating of the inverter / charger . An overcurrent protection device must be purchased separately. 1. Before using the unit, read all instructions and cautionary markings on this unit, the batteries, the solar modules, any connected loads. 2. Please do not disassemble or attempt to repair Phocos products. This unit does not contain user serviceable parts. Damage to the warranty seal will lead to a loss of warranty of the product and can lead to injury. 3. To reduce risk of electric shock, disconnect all wirings before attempting any maintenance or cleaning. Switching off the unit is not sufficient, turn off and / or disconnect all connections to the unit. 4. For safe operation of this unit, please adhere to appropriate cable size requirements in this manual.

www.phocos.com 3 | Page 5. Usage of insulated tools around the unit is strongly recommended. Be very cautious when working with uninsulated metal tools on or around batteries. They can short-circuit batteries or other electrical parts and could cause an explosion and / or injury. 6. Strictly follow the installation procedure when connecting or disconnecting AC or DC terminals. Please refer to the “Installation” section of this manual for details. 7. Appropriate fuses or breakers are required near the battery supply and AC input and AC output of this unit. 8. WARNING: It is highly recommended and legally required in many countries to install a Type B residual current device (RCD) between the AC output of the unit(s) and the AC loads to protect humans from hazardous electric shock due to faulty AC wiring, faulty loads or a potential inverter fault. Only in Off-Grid mode, the neutral (N) and ground (PE) of the AC output are automatically bridged inside the Any-Grid to ensure the RCD’s functioning if the AC installation is wired correctly as a TN-S or TN-C-S earthing system. In a TN-C-S installation the bridge between neutral (N) and ground (PE) must be between the public grid and AC input of the Any-Grid to ensure that there is never more than one bridge between N and PE. This unit is not designed to be operated in environments where an RCD is present between this unit and the AC source. 9. Never allow any AC or DC connections to be short-circuited. Do not connect to the mains when the battery input is short-circuited. 10. Only qualified service persons may service this device. If errors persist after following the “Troubleshooting” section in this manual, please send this unit back to a local Phocos dealer or service center for maintenance. 11. WARNING: Only solar panels are acceptable for use which do not require positive grounding as only grounding of the negative PV cables is allowed, if necessary. Grounding of the PV module frame is permitted and frequently required by local law. The MPPT solar charge controller is not galvanically isolated from the battery, but is isolated from the inverter. The battery is galvanically isolated from the inverter, therefore the battery positive or negative terminal may be grounded if required. 12. CAUTION: It is highly recommended to use a surge arrester, also named surge protective device (SPD) near the PV input terminals of this unit. This is to prevent damage to the unit from lightning, thunderstorms or other voltage surges on the PV cables. The max. DC operating voltage of the SPD must be between 145 and 160 Vdc. For example the
Citel DS240-110DC is suitable. 13. CAUTION: It is highly recommended to use a surge arrester, also named surge protective device (SPD) near the AC input terminals of this unit, if the AC input is used. This is to prevent damage to the unit from lightning, thunderstorms or other voltage surges on the AC input conductors (for example coming from the public grid). The max. AC operating voltage of the SPD must be between 275 and 300 Vac for 230 Vac models. For example, the
Citel DS41S-230 (for most public grids or generators, higher protection) or Citel DS41S-320 (for public grids with large voltage swings, lower protection) are suitable. When using with a 110 ~ 127 Vac AC source the SPD must have a max. AC operating voltage between 140 and 150 Vac. For example, the
Citel DS41S-120 is suitable. 3.0 Regulatory Information This product is CE and RoHS (Restriction of Hazardous Substances) compliant. Please find the CE declaration at www.phocos.com.

www.phocos.com 4 | Page 4.0 Overview Functional Overview This pure sine wave battery inverter charger with solar charge controller (MPPT) can provide power to connected loads by utilizing PV power, AC power and battery power. Most connections are optional, but there must be at least one power source (AC or PV) and battery connected: Fig. 1: System Overview This unit has one each of the following power connections: battery, PV, AC input, AC output. The unit is designed to provide continuous power from PV / battery or an AC source, depending on the set priority. Independently, the priority for charging the battery can be set (the battery can only be charged from AC when the unit is not working in Off-Grid mode). The switching time between Grid (also valid when an AC generator is used) and Off-Grid modes is only 10 milliseconds (typical). In Grid mode the unit can pass AC power from the AC source to AC loads. PV power is only charged into the battery in this mode. In Off-Grid mode the AC loads are supplied by PV power and if not sufficient, also by the battery via the inverter. It is not possible to power AC loads with PV power and power for the AC source at the same time, only to switch back and forth between these sources. The pure sine wave AC output and the surge power capability (twice the continuous power rating) assure all types of AC loads can be powered. Ensure that the peak power requirement of the loads is below the surge power capability of this inverter.

www.phocos.com 15 | Page Settings menus Menu no. Description Selectable Option and Notes 00 Exit setting mode Escape 01 AC output source priority: Configure the priority of which power sources supply the AC output load Solar first Solar provides power to the loads as first priority. If solar power is not sufficient to power all connected loads, battery power will supply the loads simultaneously (Off-Grid mode). If no solar power is available (ex. at night), or the battery voltage reaches the setting point in settings menu 12, AC input / utility power is used exclusively. During this time any PV power available is used to charge the battery. With unavailable solar power the battery is only discharged (apart from unit self-consumption) when the AC input / utility power is unavailable (Off-Grid mode). Utility / AC input first (Default) AC input / utility will provide power to the loads as first priority (Grid mode). Solar and battery will provide power to the loads only when utility power is not available (Off-Grid mode). SBU priority “SBU” for: Solar  Battery  Utility Solar powers the loads as first priority. If solar power is not sufficient to power all connected loads, the battery will supply power to the loads simultaneously. The Any-Grid is disconnected from the grid at this time (Off-Grid mode). AC input / utility provides power to the loads (Grid mode) only when the battery voltage drops to either low-level warning voltage or the setting point in settings menu 12. In this case the loads are powered only from the AC source. Any PV power is used to charge the battery while in Grid mode.

www.phocos.com 16 | Page 02 Maximum total battery charging current of AC and solar charging combined: Max. total charging current = AC input charging current + solar charging current This setting is important to limit charging current for some battery types. 10A 60A (Default) Can be set from 10 ~ 120 Adc in 10 Adc increments. This is the battery-side DC charging current. 03 AC input voltage range In addition to wider voltage tolerance, “Appliances” setting also allows more deformed sine-waves to be accepted at the AC input compared to “UPS” mode. Appliances Accepted AC input voltage range from 90 ~ 280 Vac if settings menu 10 is set from 220 ~ 240 Vac. 80 ~ 140 Vac if settings menu 10 is set from 110 ~ 127 Vac UPS (Default) Accepted AC input voltage range from 170 ~ 280 Vac if settings menu 10 is set from 220 ~ 240 Vac. 90 ~ 140 Vac if settings menu 10 is set from 110 ~ 127 Vac 05 Battery type Settings menus 26, 27 and 29 can only be modified if “User-defined” is selected here AGM (Default) Flooded User-defined Battery charging voltages and low voltage disconnect (LVD) can be manually defined in settings menu 26, 27 and 29. 06 Automatic restart if an AC output overload occurs Restart disabled (Default) Restart enabled 07 Automatic restart when over-temperature occurs Restart disabled (Default) Restart enabled 09 AC output frequency Only relevant for Off-Grid mode 50 Hz (Default) 60 Hz

Any modification between 110/120/127 Vac and 220/230/240 Vac will be effective only after the inverter is restarted. 230 Vac (Default) Available values: 110, 120, 127, 220, 230 and 240 Vac. 11 Maximum AC source charging current (battery side) If settings menu 02 is smaller than this value, charging will be limited by the value in settings menu 02. 30 Adc (Default) Available values: 2 Adc and 10 ~ 60 Adc in 10 Adc increments. 12 Voltage set-point to switch from Off-Grid mode to Grid mode when “SBU priority” or “Solar first” is selected in settings menu 01. 24 Vdc (Default) 48.0 Available values: 44.0 ~ 47.0 Vdc in 1.0 Vdc increments. 13 Voltage set-point to switch from Grid mode to Off-Grid mode when selecting “SBU priority” or “Solar first” in settings menu 01. Battery fully charged 54 Vdc (Default) 54.0 Available values: “FULL” and 48.0 ~ 61.0 in 1.0 Vdc increments. The battery is considered fully charged when the float charging phase is reached. 16 Battery charger source priority Configure the priority of which power sources are used to charge the battery. The AC source can only charge the battery if in Grid, Stand-By or Fault modes. In Off-Grid mode only solar / PV power can charge the battery. It is recommended not to choose “Only Solar” if an AC source is available because the self-consumption of the Any-Grid unit is supplied from the battery. If there are long periods without sunshine (ex. snow), the unit may shut down due to low battery voltage. Instead, select “Solar first” here and 2 Adc in settings menu 11 to compensate for the self-consumption with some safety margin. Solar first Solar power will charge battery as first priority. Utility / AC source will charge battery only when solar energy is not available and the unit is in Grid mode. Utility first Utility / AC source will charge battery as first priority. Solar power will charge battery only when no AC source is available. Solar and Utility (Default) Solar power and AC input power will charge battery at the same time if the unit is in Grid mode. Only Solar Solar power will be the only battery charging source, regardless of the operating mode.

The low DC / battery warning voltage is 2 Vdc above this setting. This value must be set at least 4 Vdc lower than settings menu 30. 44.0 Vdc (Default) 44.0 If “User-defined” is selected in settings menu 05, this value can be changed. Available values: 37.5 ~ 54.0 Vdc in 0.1 Vdc increments. This voltage is fixed and independent of the load power level. 30 Low voltage reconnect If the AC output is turned off due to low voltage disconnect (settings menu 29), the AC output is automatically turned back on once this voltage is reached. This value must be at most 0.5 Vdc below settings menu 27, and at least 4 Vdc higher than settings menu 29. 54.7 Vdc (Default) 54.7 If “User-defined” is selected in settings menu 05, this value can be changed. Available values: 51.6 ~ 60.5 Vdc in 0.1 Vdc increments. 32 Boost battery charging duration The duration for which the boost voltage from settings menu 26 is held before the Floating phase is reached. Automatic 120 min (Default) If “User-defined” is selected in settings menu 05, this value can be changed. Available values: “Automatic” and 5 ~ 900 minutes in 5 min. increments. If “Automatic” is set, the duration of bulk phase (see chapter “Specifications”  “Battery Charging”) is multiplied by 10, with a minimum of 10 minutes and maximum of 8 hours. 33 Battery equalization Battery equalization helps prevent sulfation of lead-acid batteries and is beneficial for bringing all cells to the same voltage. Consult your battery manual to make sure the battery can withstand the higher voltages required for this purpose. This is typically the case for flooded lead-acid batteries. Enabled Disabled (Default) If “User-defined” or “Flooded” is selected in settings menu 05, this value can be changed. 34 Battery equalization voltage 59.2 Vdc (Default) 59.2 Available values: 48.0 ~ 61.0 Vdc increments.
