3. Considering the need of the Indian Customers, LOBEL have introduced a unique feature of the Inverter Battery
Power Management using a specific pattern of electricity utilization from Solar Panel and Mains Supply Lines.
This pattern is developed after rigorous surveys conducted across the country, both in rural and urban areas, to
understand the power demands, availability of electricity supply and average solar energy available from
moderately efficient solar panels.
The protocol thus developed, when bundled with the Pure Sinewave Inverters, renders a major benefit to the
customer in achieving considerable reduction in his electricity bill.
What follows is a brief explanation of this protocol:
1. 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.
2. 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.
3. 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.
4. 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.
5. If Mains supply cuts off during the solar zone, the unit maintains its “solar-zone” mode. Therefore,
when the Mains supply resumes, the unit continues to operate in Inverter mode and the load is supplied
by the battery.
6. 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.
7. When Mains & Solar Power both are not available inv will start working on battery mode
8. When the battery voltage is below 10.5V, the unit enters a shut down.
