I recently installed an Axpert (mecer branded) 5kva hybrid inverter. I have an initial battery backup of 4 x 200Ah Gamistar deep cycle gel batteries. I have not installed any PV as yet .......will do some time in the next few months. so the system as is is just used during load shedding for a few lights, 2 Tvs, fridge, modem and dstv. Could someone please give me the optimal settings for this initial setup as per the programing sheet/menu. Using the software that came with inverter. Thanks in advance.
