Solar PCU

When the single battery voltage is between 10.5 V to 12 V, the
inverter unit selects the Mains supply line or Solar Power as the source of
charging. Even if the Mains supply is available
But solar power is strong inv will charge batteries on solar only & The load
is connected to the Mains (if present) in this mode
Between 12V to 14V, the battery is charged using the Solar Supply (if
present), even if the Mains is present. The load is on Mains in this mode.
When the battery voltage reaches 14.2V, the unit switches over to
the Inverter mode, charging continues from the solar supply and the load
gets shifted from Mains to the Battery(the INV ON indicator lights up) , even
if the Mains is present (the Mains Indicator starts flashing to show the
presence of Mains). The unit is then supposed to have entered into SOLAR
ZONE. In this zone, the Solar energy stored in the battery is utilized, saving
the electricity
At battery voltage 14.2 V, the charging(either from Solar or from
Mains) stops, then starts again when it falls down to 13.8V(when Solar
present), again stops at 14.2 V. This is the trickle charging operation
If Mains supply cuts off during the solar zone, the unit maintains its
���¢�¯�¿�½�¯�¿�½solar-zone���¢�¯�¿�½�¯�¿�½ mode. Therefore, when the Mains supply resumes, the unit
continues to operate in Inverter mode and the load is supplied by the
battery.
When the battery voltage reaches 11.5V per battery during the
solar zone, the unit switches back to the Mains Supply, the charging
continues from solar supply and the load gets shifted back on Mains Supply
When Mains & Solar Power both are not available inv will start
working on battery mode
When the battery voltage is below 10.5V, the unit enters a shut
down
