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 inside of package: Ÿ The unit x 1 Ÿ User manual x 1 Ÿ Communication cable x 1 Ÿ... -
Page 7: Battery Connection
Install the unit by screwing three 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. - Page 8 Please follow below steps to implement battery connection: 1. Assemble battery ring terminal based on recommended battery cable and terminal size. 2. 1KVA model supports 12VDC system, 2KVA/3KVA model supports 24VDC system and 4KVA/5KVA model supports 48VDC system. Connect all battery packs as below chart. It’s suggested to connect at least 100Ah capacity battery for 1-3KVA model and at least 200Ah capacity battery for 4KVA/5KVA model.

Page 9: Ac Input/Output Connection
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 10A for 1KVA, 20A for 2KVA, 32A for 3KVA , 40A for 4KVA and 50A for 5KVA. -
Page 10: Pv Connection (Only Apply For The Model With Solar Charger)
WARNING: Be sure that AC power source is disconnected before attempting to hardwire it to the unit. 4. Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws. Be sure to connect PE protective conductor ( ) first. - Page 11 PV Module Selection: WARNING! This inverter is only compatible with PV module types of single crystalline and poly crystalline. 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.
