Givenergy vs Huawei

Options
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. Buckinghamshire.

    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.

    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. 
    -  10 x 400w LG + 6 x 550W SHARP BiFacial Panels + SE 3680 HD Wave Inverter + SE Optimizers. SE London.
    -  Triple aspect. (22% ENE/ 33% SSE/ 45% WSW)
    -  Viessmann 200-W on Advanced Weather Comp. (the most efficient gas boiler sold)

    Feel free to DM me if I can help with any energy saving!

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