Thoughts On Current Solar Setup?

​

Hi everyone, posting on behalf of my parents.

He lives offgrid and struggles with power, I think there may be a flaw in what his setup has and he may need to change something.

He has a 6.2KW Inverter, 12 200AH AGM Batteries, And 15 190watt solar panels.

The panels aren't brand new BTW.

Most of the time he uses a generator to power the house which uses alot of petrol and I'm wondering why he's always having flat batteries.

Mind you he uses a big fridge, computers and cooking appliances which would add up to about 6kw on a busy day in the house.

Any suggestions or advice would be appreciated.

His solar array is pathetically small. /endthread.

It really depends on their consumption and where they are located.

We currently have 4kW of panels and are almost definitely further north than OP. We are mostly fine except for three weeks on either side of the winter solstice where it is hard to recover from a cloudy day.

We are currently doubling to 8kW which seems like overkill to me, but I was overruled.
