EcoGen Theory of Operation

In an off-grid solution, the generator is an important
source of backup power when other resources are insuf-
ficient for the demand, improving overall system reliabil-
ity.
1. Solar cells and/or wind turbines generate DC cur-
rent.
2. DC current is fed to the inverter charger and then
to the battery bank.
3. The inverter takes DC power from the battery bank,
converts it to AC, and then sends the current to the
AC electrical panel.
4. If there is no solar or wind gain and the battery
bank level drops below a preset threshold, the
inverter automatically signals the generator to start.
5. The generator feeds AC power to the inverter,
which in turn sends power to the electric panel and
recharges the battery bank to an acceptable level.
