Growatt or Solar edge

401 Posts

Hello,
Just about to push the button on solar and my favorite quote so far I have a choice between 2 x 6.3kwh Growatt batteries or a 10Kwh Solaredge batteries(the new Energy bank one). My PV system needs optimisers due to multiple roofs and shading.
The Solaredge battery is about £1k more expensive and less capacity 9.7kwh vs 11.7kwh but the Solaredge is more efficient ,better integrated and less boxes on the wall (1 vs 3) so neater .
Has anyone got any thoughts on this choice ?
Cheers

It you go with a Solaredge system and a growatt AC coupled inverter, then you will be going DC to AC to DC to AC.
It would be interesting to know if anyone has done a comparison of the difference in roundtrip loses. But a finger in the air guess should be around 10-20%.
I have a Solaredge inverter and optimisers. In hindsight I would have gone with Tigo optimisers and a hybrid inverter - probably Givenergy
The Growatt not so sure on the efficiency I'm guessing not as good.

I replaced my inverter with a Growatt recently - good price, painless install etc. The documentation and software is poorly translated - with the inverter web software appearing quite stale. I fired off a support query which went unanswered. I'd certainly not want to tackle a warranty claim.
Tigo monitoring/optimisers on all panels, Growatt MIC 2000 TL-X Inverter and Solar iBoost installed 2022.

While I'm not a fan of products that are made in China, I realize that these are a more pragmatic, often unavoidable middle ground. When so, always go by the brand's reputation. That said, I would pick a component made in Japan or Korea, every single day of the week, if the option existed.
