I have a Mecer SOL-i-AX-3VP 3kw inverter with 2x100ah AGM batteries and 4x330W PV Panels. Only as a backup for 1xBosch fridge, 1xBosch freezer, 1xSmall chest freezer, all lights and plugs(including tv), accept micro wave, DW, WM, kettle, toaster, airfryer, stove and geyser. I experience the following. At about 18h00, when pv panels have no more sun while loading the batteries, when switching to eskom, led lights dip for a second and the tv also shut down and come on again. The same happens when loadshedding start and the systems needs to switch over to the inverter/batteries system. This can not be right. Will appreciate any recommendation to rectify this.

If setting 3 is not on UPS change it from APL and switch off the inverter and back on. Then give yourself LS and see if things improve. 

Just ensure all your fridges and freezers are off before you do these within 3min on and off switching. 

Just my 2c. The batteries are only good to use 1200Wh being 24V at 50Ah which is 50% of power. During the 4 hrs after say 4hrs of LS they will not charge enough before the next LS say after another 4hrs. This will kill the in a short period unless you have the inverter set to cut out at 23.6 to 24V.
