Solar Inverter

I have a small test solar system that I run a few things off.
It stopped working.

Did not take long after opening it to find out why.
Pretty poorly built really. I should have opened it from new and would have seen trouble coming before we put it into service.
There is no way this thing is rated for the 600 watts it was sold as.
In a way, it did me a favour. Freddy approved a new 1000 watt version and it really is rated at that. As such, the efficiency of the unit is much higher and I am getting more power than ever and have changed nothing but the inverter.
