I'm guessing the fentanyl addicts sold off my solar panels last winter. It was a long hard winter for affordability. 😮

I'm already on my second system as the first panels (op down to under 50%) and Inverter failed within 3 years.

Second time round,

Just use it as grid tie and wind my meter back.

Still using the old battery from the first install for a bit of emergency power.

Power production the past 2 months down to 60% due to bad weather.

Given my own experiences with my ‘MUST’ inverters, which are performing less and less well and causing more and more problems, I would like to know what brand your previous inverter was, and which brand your new inverter is.

I buy PowMr inverters (7kbht for 6k2 inverter), because they come with a 3 year warrenty and are cheap enough to replace every 3+ years.

I'd check your solar panels output, they fail much quicker than expected, the inverters usually go out with a bang!

Ik zou de output van je zonnepanelen controleren, ze falen veel sneller dan verwacht, de omvormers gaan meestal met een knal naar buiten!

That’s right, I’d already had my doubts about that too – in full sunlight, less voltage is output than when the sun is obscured.

I have two sets of panels, one set of 540 W and one set of 455 W; they now both output the same voltage.

But then again, it’s not just the inverters and solar panels but also the batteries – two sets, each of which I paid 42,000 THB for five years ago. It’s the convenience they offer – no power or voltage cuts – but you certainly wouldn’t do it for the cost alone.
