Givenergy vs Huawei

Magnitio

I was due to have a solar installation in a few weeks with an 8.2kwh Givenergy battery. Just been notified that there are shipping delays and have been offered the choice of waiting another 4-6 weeks or having a Huawei 10kwh battery and Huawei hybrid inverter for an additional £1k. Does anyone have experience of the Huawei batteries and inverters?

I didn't know Huawei marketed solar and batteries here. On the basis that they were supplying a great deal of our mobile phone and broadband infrastructure, before the "spying" scare, I would imagine thir kit is well built.

I think later updates he's highlighted poor low light performance from the Huawei though...

Yes startup voltage for the inverter is relatively high. 

Magnitio

From the spec sheets it appears both have a 100V startup voltage. I'm not experienced enough to know how much of an issue that is.

I've watched some of the videos from The EV Puzzle, but I think some software and user issues cloud his judgement at times. He certainly rated the Huawei installation more highly than Givenergy, but I understand that the latter's software has improved since his tests.

Did you happen to notice what the MPPT ranges are for each inverter?

90 V – 560 V for Huawei

120 V - 550 V for Givenergy

That would make me think the huawei is more likely to generate in low light than the givenergy.

That low-light generation really makes minimal difference overall. Probably less than 5kWh over a year when you calculate it.

Just something to think about when you consider Huawei. Not all costs are upfront!

I would stick with Givenergy.

Yes, it would come as quite a shock to me to find out I was Uighur.
