Surprised not to have found any topic on this yet... Sermatec 5kW hybrid inverter: On paper / specs this looks very similar to the Goodwe - but slightly cheaper. Spec sheet here Anyone worked with one of these yet? How does it compare? Specifically to the Goodwe? Local support?

From what I can tell - you would need a SMA Sunnyboy grid-tie PV inverter, PLUS a Sunnyboy Storage Battery inverter... Check this pic Amazes me - SMA is an awesome product (from what I've been told) but they don't exactly make it easy to understand their system and options. I find the same with Victron - as an end user I want an easy to understand schematic of what my options are and what "modules" I would need for the setup, but such info one has to dig up from various sources...

Hey guys, Been doing a lot of reading here - some brilliant advice and posts. I'm looking at installing a hybrid system - around 4.5kW Inverter, 3.6kWp PV and probably 2 Pylontech 3000s, largely DIY. So here's the question - what brand inverter? Leaning towards the Goodwe as a brilliant little all-rounder. Seems to include all function we require in one unit, good quality, easy install, and all at a pretty reasonable price. But what would we be missing out on compared to the competition? Thinking specifically Victron and/or SMA - what extra features and enhancements do these offer over the Goodwe? I hear the Goodwe is a little limited in the setup / programming one can do - this'd be a serious drawback for me. Are the others worth the extra expense and complexity? (As I understand both these other systems one would need seperate modular units as opposed to Goodwe all-in-one) Would really appreciate your guys' reasons for preferring one over the other...

Thank you @wolfandy, I am in Pretoria, not Cape Town. Power from CoTshwane. However. From what I can tell that 25% rule is a NRS097 rule, not Cape Town specific, I.o.w. the whole country needs to abide by it? And if it is indeed the whole country; how strict are they about it - can one generally get away with it or are you looking at replacing the inverter (or scaling down on installed panels) down the road? If not whole country, but similar laws to be introduced in future, will existing systems be exempt from this rule? Am I stressing about nothing or should I look at complying with max 3.5KW on my 60A MCB? (I note that many solar installers will happily quote me on a 5KW system)...

Hi guys, very glad to have found this forum, some real good gen here. However I couldn't find a definitive answer to this Q... We have a 60A main circuit breaker. This limits our inverter to max 3.5KW, right? Does same apply even if not feeding back to Eksdom? Or is this rule only applied to feed-in systems? Thanks, Markus
