hI. IM NEW TO THE FORUM. I bought a Mecer Hybrid 5Kva / 5000. I was told that some lithium ion 4.8kwh 48v batteries are not compatible with Mecer. ANy suggestions on which battery type will be compatible. Apparently Mecer battery is not available. Will appreciate advice and suppliers as there are many scam suppliers out there. Thanks in Advance. I am new to this inverter setup
