Two Inverters on one Battery Bank
When connecting multiple inverters to a single battery bank, you can either use synchronized inverters for the same load or separate inverters for different loads. It''s important
connecting an inverter with the battery will not do the harm to your battery while it's charging unless the battery is about to fully drained or it has reached its discharged limit like a lead-acid battery which only has a DOD limit of 50% Is it safe?
Connecting two inverters to the same battery is easy. But there are some extra calculations and considerations we need to do. The C-rate is how fast a battery can discharge. For example, a 12V, 100Ah lead-acid battery has a c-rate of 0.2. This means you can discharge the battery at 20 amps to achieve a long battery lifespan.
The only difference is the setting on your charging controller, which we will start to review now. Solar power is the most common way to charge your battery while connected to an inverter. It acts as a battery charger that provides constant voltage to keep your battery charging.
Let's say you have a 2000W inverter and want to add another 1000W inverter. You need a 12V, 250Ah battery to support a 3000W inverter power. Proper wiring and safety precautions are essential when connecting multiple inverters to a single battery bank. Use appropriately sized cables, fuses, and circuit breakers to ensure a safe and efficient setup.
