Getting more power from a portable solar panel system.

[Johandup]

Some time ago I bought portable 200w solar panels from Outdoor Warehouse.

I am camping now in the Kruger and don't get more than 80w from it.

The challenge is my normal caravan fridge consumes 130w.

Is it normal and what I can I do to get 150w from it?

In a week's time I'll be in Tzendze where there is no power.

I am looking at buying some 4 x 100w glass solar panels to get to the watts required.

My intention is to charge a Gizzu Challenger Max 1000W / 835Wh Ups Power Station Lifepo4 from the solar panels while it powers the caravan fridge.

Just a question. Is the Gizzu powering your caravan 230V fridge. Not sure about this power station but most are not intended to be used as a UPS or if there is no grid. They great for about 1hr a day with no power. 

Getting only 80W from a 200W shows there is a problem on the panel and I would return it if you can. 

The power from 4x100W should just make it on a sunshine day but you are running very marginal to draw 130W plus the over 1400W to start a 230V fridge say 12+ times after sunset. You would also need some very good batteries to do it at Tzendze.
