June 28, 20242 yr Hi everyone. I know this sounds crazy, but I have two inverters with the same model and brand, a 3.5Kw and 5.5Kw, both with the exact same controller, same firmware with different values for sure. So, is it possible to convert the 5.5kw to work with 24v batteries instead of 48v without problems?
June 28, 20242 yr you need the 24V in series to make 48V and then using Voltage as the charging method on the 5.5kw. Which inverter do you? Deye or Sunsynk? Also check if the batteries can be connected in series, some manufacturers do not recommend it Edited June 28, 20242 yr by Jakac checks
June 28, 20242 yr Also, adding to the answer from Jakac, if you have batteries in series you will also need a battery balancer.

If you mean can you easily convert a 48 V inverter into a 24 V inverter, the short answer is no. You would need a different transformer turns ratio, dozens of different parts, different firmware, it's endless. Edited June 28, 20242 yr by Coulomb

Yes that exactly what i meant, thanks for the quick answer, actually I'm working on updating the firmware of 150+ Sorotec inverters of both 3.5 and 5.5kw, and in fact what wondering me is I heared that someone was able to convert a 48v inverter to 24v (I believe it's voltronic) but I didn't know how, and waiting the answer from who told me this. I'll keep you posted if a get a clear answer. Edited June 28, 20242 yr by AMalakani

With a quick thinking, the only easy way (a shortcut) that came to my mind is to use a DC-DC step-down circuit to lower battery voltage from 48 to 24. I don't know, but anyways it's a completely wrong practice.
