Givenergy vs Huawei

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?
6.4kWp (16 * 400Wp REC Alpha) facing ESE + 5kW Huawei inverter + 10kWh Huawei battery. Vaillant Arotherm Pro 7kW heat pump.

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...1 -
Yes startup voltage for the inverter is relatively high.4.29kWp Solar system, 45/55 South/West split in cloudy rainy Cumbria.1

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.6.4kWp (16 * 400Wp REC Alpha) facing ESE + 5kW Huawei inverter + 10kWh Huawei battery.

That would make me think the huawei is more likely to generate in low light than the givenergy.4.29kWp Solar system, 45/55 South/West split in cloudy rainy Cumbria.1

That low-light generation really makes minimal difference overall. Probably less than 5kWh over a year when you calculate it.0

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

I would stick with Givenergy.- 10 x 400w LG Bifacial + 6 x 550W SHARP BiFacial + 2 x 570W SHARP Bifacial + 5kW SolarEdge Inverter + SolarEdge Optimizers. SE London.

Yes, it would come as quite a shock to me to find out I was Uighur.Screwdriva said:Just something to think about when you consider Huawei. Not all costs are upfront!
