I am running an Esener Inverter on two Esener 5.12kwh batteries - no issues the last year +
ES-5248 PRO+ Inverter and 2x ES-5.12KWH batteries
Getting a second Inverter and another battery as we speak - because it over performs my expectations in terms of charging and I am increasing my system capacity.
There is a Chinese guy (Kevin) from Esener in South Africa that does support on settings and cabling, etc, works great on text translations (no voice comms)
For small installs, I would definitely suggest the Esener brand - the battery and the Inverter speak perfectly to each other.
