No! you can not use it directly because it has inbuilt AC charging whereas DC charging is needed for solar.
But you can do it the “Jugaad” way:
- Buy Solar charge controller with an changeover with AC but priority solar. The Solar charge controller’s battery output DC voltage & current specifications should exactly match the DC voltage & current specification of inverter’s AC charger & the charging algorithm shall be almost similar!
- Ask Inverter’s service engineer to remove the inbuilt AC charging circuit and connect the new Solar Charger.
Caution:
- The warranty of inverter & charge controller will become Void. So it is advisable to do it after warranty period or buy another off-grid solar inverter.
- If specifications do not match then the inverter will not work!
