700W 24V Solar Inverter with MPPT Charge Controller

Solar Inverter with MPPT Charge Controller User Manual

What are the DC battery preferred mode of solar inverter with MPPT charge controller?

1. Bulk Charging Mode:
   In this mode, the MPPT charge controller charges the battery at the maximum current allowed, using the solar energy that’s available. The system attempts to charge the battery as quickly as possible, usually until the battery voltage reaches a set point (typically the battery's absorption voltage).
2. Absorption Mode:
   After the battery reaches a set voltage (usually slightly above its nominal voltage), the solar charge controller reduces the charging current to avoid overcharging the battery. The inverter in this mode maintains the battery at the absorption voltage for a while to ensure it is fully charged without damaging the cells.
3. Float Mode:
   When the battery reaches its full charge, the MPPT charge controller switches to float mode. In this mode, the charging voltage of mppt solar charger is reduced to a level that maintains the battery at full charge without overcharging it. This helps to preserve battery life by keeping it topped off but not continuously overcharged.
4. Equalization Mode (if applicable):
   Some systems also use an equalization mode, typically as a maintenance phase, to ensure all the battery cells are balanced. It involves overcharging the battery briefly to allow the electrolyte to mix and equalize the charge across the cells. This is generally used on lead-acid batteries.
5. Discharge Mode:
   When solar power production is insufficient to meet the load demand (for example, during cloudy days or at night), the system switches to discharge mode. In this mode, the inverter pulls energy from the battery to supply power to the connected load.
