2. Safety
2.1 Appropriate Usage
This inverter is designed and tested in accordance with international safety requirements. However, certain safety
precautions must be taken when installing and operating this inverter. The installer must read and follow all instructions,
cautions and warnings in this installation manual.
- All operations including transport, installation, start-up and maintenance, must be carried out by qualified, trained
personnel.
- The electrical installation and maintenance of the inverter shall be conducted by a licensed electrician and must
comply with local wiring rules and regulations.
- Before installation, check the unit to ensure it is free of any transport or handling damage, which could affect
insulation integrity or safety clearances. Choose the installation location carefully and adhere to specified cooling
requirements. Unauthorised removal of necessary protections, improper use, incorrect installation and operation
may lead to serious safety and shock hazards or equipment damage.
- Before connecting the inverter to the power distribution grid, contact the local power distribution grid company to
get appropriate approvals. This connection must be made only by qualified technical personnel.
- Do not install the equipment in adverse environmental conditions, such as in close proximity to flammable or
explosive substances, in a corrosive environment, where there is exposure to extreme high or low temperatures,
or where humidity is high.
- Do not use the equipment when the safety devices do not work or are disabled.
- Use personal protective equipment (PPE), including gloves and eye protection during the installation.
- Inform the manufacturer about non-standard installation conditions.
- Do not use the equipment if any operating anomalies are found. Avoid temporary repairs.
- All repairs should be carried out using only approved spare parts, which must be installed in accordance with
their intended use and by a licensed contractor or authorised service representative.
- Liabilities arising from commercial components are delegated to their respective manufacturers.
- Any time the inverter has been disconnected from the public network, please be extremely cautious as some
components can retain charge sufficient to create a shock hazard. Prior to touching any part of the inverter please
ensure surfaces and equipment are under touch safe temperatures and voltage potentials before proceeding.
2.2 PE Connection and Leakage Current
PV System Residual Current Factors

________________________________________________________________________________________________________
Energizer Solar Inverter | Installer Manual [4]
- In every photovoltaic (PV) installation, several elements contribute to the current leakage to protective earth (PE).
These elements can be divided into two main types.
- Capacitive discharge current - Discharge current is generated mainly by the parasitic capacitance of the
PV modules to PE. The module type, the environmental conditions (rain, humidity) and even the distance of
the modules from the roof can affect the discharge current. Other factors that may contribute to the parasitic
capacitance are the inverter’s internal capacitance to PE and external protection elements such as lighting
protection.
- During operation, the DC bus is connected to the alternating current grid via the inverter. Thus, a portion of the
alternating voltage amplitude arrives at the DC bus. The fluctuating voltage constantly changes the charge state
of the parasitic PV capacitor (i.e capacitance to PE). This is associated with a displacement current, which is
proportional to the capacitance and the applied voltage amplitude.
- Residual current - If there is a fault, such as defective insulation, where an energized cable comes into contact
with a grounded person, an additional current flows, known as a residual current.
Residual Current Device (RCD)
All Energizer solar inverters incorporate a certified internal RCD (Residual Current Device) to protect against possible
electrocution in case of a malfunction of the PV array, cables or inverter (DC). The RCD in Energizer solar inverters
can detect leakage on the DC side. There are 2 trip thresholds for the RCD as required by the DIN VDE 0126-1-1
standard. A low threshold is used to protect against rapid changes in leakage typical of direct contact by people. A
higher threshold is used for slowly rising leakage currents, to limit the current in grounding conductors for the safety.
The default value for higher speed personal protection is 30mA, and 300mA per unit for lower speed fire safety.
Installation and Selection of an External RCD device
An external RCD is required in some countries. The installer must check which type of RCD is required by the specific
local electric codes. Installation of an RCD must always be conducted in accordance with local codes and standards.
For this inverter, the use of a type-A RCD is recommended. Unless a lower value is required by the specific local
electric codes, then an RCD value between 100mA and 300mA is recommended.
In installations where the local electric code requires an RCD with a lower leakage setting, the discharge current might
result in nuisance tripping of the external RCD. The following steps are recommended to avoid nuisance tripping of
the external RCD:
1. Selecting the appropriate RCD is important for correct operation of the installation. An RCD with a rating of 30mA
may trip at a leakage as 15mA (according to IEC 61008). High quality RCDs will typically trip at a value closer to their
rating.
2. Configure the trip current of the inverter’s internal RCD to a lower value than the trip current of the external RCD.
The internal RCD will trip if the current is higher than the allowed current, but because the internal inverter RCD
automatically resets when the residual currents are low it saves the manual reset.
2.3 Surge Protection Devices (SPDs) for PV Installation
WARNING! Over-voltage protection with surge arresters should be provided when the PV power system is installed.
The grid connected inverter is not fitted with SPDs in both PV input side and mains side. Lightning will cause damage
either from a direct strike or from surges due to a nearby strike. Induced surges are the most likely cause of lightning
damage in majority or installations, especially in rural areas where electricity is usually provided by long overhead
lines. Surges may have an impact on both the PV array conduction and the AC cables leading to the building.

________________________________________________________________________________________________________
Energizer Solar Inverter | Installer Manual [5]
Specialists in lightning protection should be consulted during the end use application. By using appropriate external
lightning protection, the effect of a direct lightning strike into a building can be mitigated in a controlled way, and the
lightning current can be discharged into the ground.
Installation of SPDs to protect the inverter against mechanical damage and excessive stress include a surge arrester
in case of a building with external lightning protection system (LPS) when separation distance is kept. To protect the
DC system, a surge suppression device (SPD type2) should be fitted at the inverter end of the DC cabling and at the
array located between the inverter and the PV generator. If the voltage protection level (VP) of the surge arresters is
greater than 1100V, an additional SPD type 3 is required for surge protection for electrical devices.
To prot ec t t h e A C system, s u rge sup pr es si on d evices (S PD type2) s h o ul d be f i t t e d at t h e main i n c o ming point of AC
supply (at the consumer’s cutout), located between the inverter and the meter/distribution system; SPD (test impulse
D1) for signal line according to EN 61632-1. All DC cables should be installed to provide as short a run as possible,
and positive and negative cables of the string or main DC supply should be bundled together.
Avoid the creation of loops in the system. This requirement for short runs and bundling includes any associated earth
bundling conductors. Spark gap devices are not suitable to be used in DC circuits once conducting; they will not stop
conducting until the voltage across their terminals is typically below 30 volts.

5.9 Inverter Start-Up
Please refer to the following steps to start-up the inverter:
a) Ensure device is securely fixed on the wall.
b) Make sure all DC breakers and AC breakers are disconnected.
c) Ensure AC cable is connected to the grid correctly.
d) Ensure all PV panels are connected to the inverter correctly - DC connectors that are not used should be sealed by
a cover.
e) Turn on the external AC and DC connectors.
f) Turn the DC switch to the “ON” position (if equipped with DC switch on the inverter).
If the LED is not green, please check the following:
- All the connections are correct.
- All the external disconnect switches are closed.
- The DC switch of the inverter is in the “ON” position.
Note!
When starting the inverter for the first time, the country code will be set by default to the local settings.
Please check that the country code is correct for your region.
Set the time on the inverter using the button or by using the respective digital touchpoint e.g. LCD panel,
touch key, iOS App, Android App, or desktop web portal.
Below are the three possible inverter states indicating that the inverter has started up successfully:
Waiting: Inverter is waiting to check the DC input voltage from panels is greater than 80V (lowest start-up voltage) but less
than 120V (lowest operating voltage), display will indicate the Waiting status and green LED will flash.
Checking: Inverter will check DC input environment automatically when DC input voltage from the PV panels exceeds
120V and PV panels have enough energy to start inverter, display will indicate the Checking status and green LED will
flash.
Normal: Inverter begins to operate normally with green light on. Meanwhile feedback energy to grid, LCD displays present
output power.
Note!
You can go to t he setting interfac e on the displa y to follow the instructi ons if it is the first t ime to star t up.
• Complete inverter Start-up guide
After the initial start-up the inverter, the display will revert to the language settings page. Short press to switch languages
and long press to confirm selection. Once language has been set, the display will guide to set the safety regulation. Short
press to switch safety regulation, and long press to confirm selection.
Note!
Please set-up the inverter if it is the first time to start-up. The above steps are for the regular start-up of
the inverter. If it is the first time to start up the inverter, you need to carry-out the initial set-up of the
inverter.
