Equalize charging time and timeout
In the Equalize stage, the controller will supply power to charge the battery as much as possible until the
battery voltage raises to battery equalization voltage. Constant-voltage regulation is then applied to maintain
battery voltage at the battery equalization voltage. The battery will remain in the Equalize stage until the set
battery equalization time has come.
However, in the Equalize stage, when battery equalization time has expired and battery voltage has not risen
to the battery equalization voltage point, the charge controller will extend the battery equalization time until
the battery voltage achieves battery equalization voltage. If the battery voltage is still lower than battery
equalization voltage when battery equalization timeout setting has been reached, the charge controller will
stop equalization and return to float stage.
The M Series pure sine wave inverter/charger is built with MPPT solar charging modules up to 120A.

Note: The M12048D is built with two separate 60A MPPT controllers, each one capable of handling
different voltages and amperages from different PV arrays.
Its max charging current is not the sum of AC charge current and MPPT Charger.
The MPPT Solar Charger will automatically work when the inverter is powered off.
Even when the power switch is in the off position, the built-in solar charger will automatically work when
PV input voltage and battery voltage is in the acceptable range, this is to optimize solar production for
battery charging.
With the power switch is in the off position, the inverter will not convert battery power to AC output.
When the battery is fully charged, the voltage has to drop by 2 volts (or below 98% of SOC when BMS
communication is established) to activate the charger.
