Notice:

PV Connection (Only apply for the model with solar charger)

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's 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.

PV Module Selection: (Only for the model with PWM solar charger)

When selecting proper PV modules, please be sure to consider below requirements first:

  1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
    INVERTER MODEL HPS12V1500VA HPS24V1500VA HPS24V3000VA
    Rated Out Power 12V 24V
    Charging Current (PWM) 50Amax.
    Max. PV Array Open Circuit Voltage 55Vdc 80Vdc
  2. Max. Power Voltage (Vmpp) of PV modules should be close to best Vmp of inverter or within Vmp range to get best performance. If one PV module can not meet this requirement, itS necessary to have several PV modules in series connection. Refer to below table.
    Model Best Vmp Vmp range
    HPS12V1500VA 15Vdc 15V~20V
    HPS24V1500VA 30Vdc 30V~40V
    HPS24V3000VA

Note: * Vmp: panel max power point voltage.

The PV charging efficiency is maximized while PV system voltage is close to Best Vmp.

Maximum PV module numbers in Series: Vmpp of PV module *Xpcs = Best Vmp of Inverter or Vmp range

PV module numbers in Parallel: Max. charging current of inverter / Impp

Total PV module numbers = maximum PV module numbers in series * PV module numbers in parallel

lake HPS12V1500VA inverter as an example to select proper PV modules. After considering Voc of PV module not exceeds 55Vdc and max. Vmpp of PV module close to 15Vdc or within 15Vdc ~ 20Vdcz we can choose PV module with below specification.

Fault and Troubleshooting

 

No LCD
display when
inverter turns
on

 

First to test battery volt to check whether it is in range of 22V-26V;
If it is in the range, to switch the inverter one to check whether the unit starts. If the unit does not run yet, please disconnect all connections and open the surface panel, take out the main board, then to check and repair according to 3.6 and 3.7. If problems remains, the CPU is broken, replace the main board.

Fault 01

Fan is locked when inverter is off.

First to replace the fan, to check whether it is ok; if NO, please
inspect the main board and repair according to 3.9

Fault 02

Over temperature

Please to check the main board and repair according to 3.8

Fault 03

Battery voltage is too high

Please to check first and then to repair the main board according
to 3.1, 3.6 and 3.7

Fault 04

Battery voltage is too low

Please check the battery’s voltage. If voltage is too low, please charge it.

Fault 05

Output short circuit or over temperature is detected by internal converter components.

First to start up the inverter by only connecting battery, if the fault is still on, please inspect the main board following 3.3 and 3.4.

Fault 06

Output voltage is abnormal. (For 1K/2K/3K)
Output voltage is too high. (For 4K/5K)

First to start up the inverter by only connecting battery, if the fault is still on, please inspect the main board following 3.3.

Fault 07

Overload time out

Please turn off the loads, and restart the inverter again.

Fault 08

Bus voltage is too high

Please check the BUS circuit of the main board according to 3.5.

Fault 09

Bus soft start failed

To check the main board following 3.1.2, 3.2.1, 4.1 and 4.2 and to repair accordingly

Fault 11

Main relay failed

Please check the relay whether work.
