Hybrid Inverters: Input vs. Charge Current Guide
Maximum Solar Charge Current: This is the maximum current the inverter''s MPPT controller delivers to the battery. For example, a hybrid inverter
As the battery's SOC increases, the charging current gradually decreases. Once the battery reaches a specific voltage threshold, the inverter charger switches to absorption charging mode. In this phase, the charger maintains a constant voltage while gradually reducing the charging current. The battery continues to charge, albeit at a slower pace.
Its primary role is to manage the charging process efficiently to maintain the battery's optimal performance, the battery charger internally converts AC power into DC power for the battery. On the other hand, an inverter for battery charger operates with a broader scope.
Maximum Solar Charge Current: This is the maximum current the inverter's MPPT controller delivers to the battery. For example, a hybrid inverter may support an 80A charge current, charging a battery at up to 80A based on its voltage.
Typically, an inverter may take anywhere from 6 to 12 hours to full charge a standard tubular battery. The key influencer here is the charger's output capacity—higher capacities result in faster charging times. Conversely, UPS systems tend to charge more quickly due to their smaller battery sizes and efficient charging mechanisms.
