Incredible wave of the wand Gordon but maybe you could combine in cfinlay's 1st thread where he gives some specs for his system like a fridge that uses 250W?
Just tested the voltage output of the inverter and it is only 188v so that is probably my problem!
What's the battery voltage when you're getting 188V from the inverter? From what you've said earlier the batteries seem to be struggling, which could explain the low AC output voltage, though the inverter should really cut-out before that happens. Also, something has to grow in the generation [and battery storage] side of your system or something needs to shrink on the consumption side of your system. Maybe 1.5 kW of panels or a fridge that uses ~50 W, which is quite possible. The efficiency [read power loss] of your inverter will matter because you have to have it on 24/7 for the fridge. Even when nothing else is happening you could be using 50W just having it on standby.
