How many watts does this convert to? What size inverter is best to use?

Solar Power pun. Hee-hee. You’ll hear that one a lot from solar installers. In any case, the answer is, generally, DC STC. Huh? It would do thee well to read The Difference Between DC and AC (and PTC/STC). [...] [...] Get it? “Watt’s” the deal? Solar Power pun. Hee-hee. You’ll hear that one a lot from solar installers.

I have 8 LED strips lights which output 72 watts per strip. I would like to link all 8 strips to one transformer. Since strips are rated at 12Volt, I need to know which transformer do I need to make this work? Please help me as I am not very good at all with AC and DC conversion. Would you recommend any product and what type transformer do I need i.e AC to DC or DC to DC or something else. I been advised to get 12 Volt 600 watts transformer but dont know if it is AC to DC or what? I would highly regard your kind help. Thanks Hi there,

We have a 4.0kW (STC) system. The highest output we've seen is 3.5kW. The PTC and orientation likely account for not seeing a 4.0kW result. This explains it.
