Introduction.
Off-Grid Power System BSP 5S
BSP 5S is a smart-tech and multi-function inverter that can manage and control power usage in off grid type.
Developed using a powerful 32-bit microprocessor from Texas Instruments (USA) TMS320F2809. BSP 5S is
integrated with charger remote control module, MPPT 80A module, a high frequency pure sine wave inverter and
a UPS function module in one machine, which is perfect for off grid backup power and self-consumption applications.
The transformerless design provides reliable power conversion in compact size. The BSP uses advanced electronic
components to provide excellent power conversion with extremely compact dimensions.
The whole system also need other devices to achieve complete running such as PV modules, generator, or utility
grid. Please consult with your system integrator for other possible system architectures depending on your
requirements. The WiFi / GPRS module is a plug-.and-play monitoring device to be installed on the inverter. With
this device, users can monitor the status of the PV system from the mobile phone or from the website anytime
anywhere
BSP 5S is an ideal product for smart homes, islands and rural areas where shortage or insufficient national grid
occur. BSP 5S is proud to serve your home with green energy and ready to turn your house into a smart home.

Installation
Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have
received the following items in the package:
 The unit BSP 5S x 1
 User manual x 1
 Communication cable x 1
Preparation
Before connecting all wiring, please take off bottom cover by removing two screws as shown below.
Mounting the Unit
Consider the following points before selecting where to install:
Do not mount the inverter on flammable construction materials
 Mount on a solid surface.
 Install this inverter at eye level in order to allow the LCD
display to be read at all times.
 The ambient temperature should be between 0°C and
55°C to ensure optimal operation.
 The recommended installation position is to be adhered
to the wall vertically.
 Be sure to keep other objects and surfaces as shown in
the right diagram to guarantee sufficient heat dissipation
and to have enough space for removing wires.
SUITABLE FOR MOUNTING ON CONCRETE OR
OTHER NON-COMBUSTIBLE SURFACE ONLY

Install the unit by screwing three screws. It’s recommended to use M4 or M5 screws.
Battery Connection
CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current
protector or disconnect device between battery and inverter. It may not be requested to have a disconnect device
in some applications, however, it’s still requested to have over-current protection installed. Please refer to typical
amperage in below table as required fuse or breaker size.
Ring terminal:
WARNING! All wiring must be performed by a qualified person.
WARNING! It's very important for system safety and efficient operation to use
appropriate cable for battery connection. To reduce risk of injury, please use the
proper recommended cable and terminal size as below:

Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. Connect all battery packs as units requires. It’s suggested to connect at least 200Ah capacity battery
for 4KVA/5KVA model.
3. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts
are tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is
correctly connected and ring terminals are tightly screwed to the battery terminals.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are connected
tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure
positive (+) must be connected to positive (+) and negative (-) must be connected to negative (-).

AC Input/Output Connection
CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter
and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully
protected from over current of AC input. The recommended spec of AC breaker is 50A cho 5KVA.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input and
output connectors.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It’s very important for system safety and efficient operation to use appropriate cable for AC input
connection. To reduce risk of injury, please use the proper recommended cable size as below.
Suggested cable requirement for AC wires.
Model Gauge (mm2) Torque Value
5KVA 10 1.4~ 1.6Nm
Please follow below steps to implement AC input/output connection:
1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be
sure to connect PE protective conductor first.

5. Make sure the wires are securely connected.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility
short-circuited when these inverters are worked in parallel operation.
CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required
to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a
short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check with
manufacturer of air conditioner that if it’s equipped with time-delay function before installation. Otherwise, this off
grid solar inverter will trigger overload fault and cut off output to protect your appliance but sometimes it still
causes internal damage to the air conditioner

PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter and
PV modules.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It'’ very important for system safety and efficient operation to use appropriate cable for PV module
connection. To reduce risk of injury, please use the proper recommended cable size as below.
Model Typical Amperage Cable Size Torque
5KVA 80A 16mm2 1.4~1.6 Nm
PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter BSP 5S.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.
Solar Charging Mode
INVERTER MODEL BSP 5S - 5KVA
Max. PV Array Open Circuit Voltage 145Vdc
PV Array MPPT Voltage Range 60~115Vdc
Min. battery voltage for PV charge 34Vdc
Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Check correct polarity of connection cable from PV modules and PV input
connectors. Then, connect positive pole (+) of connection cable to positive
pole (+) of PV input connector. Connect negative pole (-) of connection
cable to negative pole (-) of PV input connector.
3. Make sure the wires are securely connected.
