LOGIC OF OPERATION
Logic of operation in Maximum Utilization Mode & Guaranteed Back Up Mode is as per following steps
Maximum Utilization Mode
- Separate MPPT SOLAR CHARGER is provided to above unit to charge batteries on SOLAR POWER.
- When SOLAR POWER is present & batteries are fully charged mains supply is disconnected. Batteries are allowed to discharged & SOLAR POWER is also utilized, Batteries are allowed to discharged upto certain limit. SOLAR CHARGER shall charges the batteries as well as feed the load.
- When SOLAR POWER is poor & batteries discharge below 1.9V /Cell, Controller turns ON mains contactor for charging batteries & providing load.
- This logic is for maximum utilization of SOLAR available power.
Guaranteed Back Up Mode
- When Guaranteed Back Up Mode is selected controller keeps batteries in charging condition, and inverter in OFF condition till mains power is available. On mains failure only inverter is switched ON and batteries are discharged. This mode is selected for guaranteed back up. This mode is recommended during low availability of SOLAR POWER.
