ALGOTECK CHARGING CURVE
BATTERY CHARGING STEPS
The ALGOTECK charging algorithm, unique on the market, is composed of 3 steps.
1
BOOST CHARGE
UNIMPPT uses 100% of the energy from the solar
panel, until the voltage reaches the equalization level.
The battery is charged at 80%.
2
EQUALIZATION
UNIMPPT equalizes the charge on all battery elements
(battery charged at 100%)
3
FLOATING
100%
The battery charge is done. The green "load" light
starts blinking. UNIMPPT continues to deliver a low
current to compensate the battery’s self-discharge.
