This Solar PCU is very useful for elevators where there is frequent power failures.
The Solar energy is used to run elevator motor and few lights as well as to charge the batteries for storage of power.
Stored power can be used for short or long time backups in case of power failure. With LCD display you can read input/output/Solar voltage, output/battery/Solar current and Solar Power.
Programming is provided to select Power source priority, Battery charging event, Battery type, Battery charging current, Grid charging level, low load shutdown etc.
