I am about to get a 4kw solar system installed next week. it is 10 panels on a south facing roof was gonna be with a basic 3.6kw inverter. i have got my self a huawei inverter sun2000 5kw as i am tempted my battery at a later date that my installer is happy to use instead of their own inverter ( it was brand new huawei unit) . I also have a EV and use the wallbox pulsar plus on it. I have picked up the wallbox power boost ct clamp so the solar can help charge my car with the excess electric generated. I have been reading about the Huawei smart power sensor that I did not get wit the inverter seems to be an extra accessory. Can anyone advise is it needed its seems it is a ct clamp with digital screen. 2nd question was having a look at the growatt gbli5001 battery as i have seen a few listed on ebay. Does it need the growatt sp2000 also i think its an inverter or would the battery box plug into my Huawei inverter right away.

Also will have an iboost fitted for water heating.

Any information would be great im like a sponge trying to take it all in at moment.

Hi. You'll love the solar panels. All very exciting. I have a similar setup with ev charging and water heating from excess electric. I have recently bought (second hand) the Growatt SP2000 & GBLI5001 (5kwh) battery. I believe the GBLI5001 only works with Growatt chargers (there's a few to choose from). The SP2000 isn't really an inverter, it a battery charger that manages the flow of electric from the PV panels. You still need your inverter. Have a quick search on internet you'll find a pictorial diagram of a normal setup. I might be wrong with the battery only working with Growatt chargers/inverters. An all-in-one inverter and charger would be better I think. I have since broken my SP2000 so now it doesnt charge the battery! My fault. The SP2000 & GBLI5001 aren't very configurable and there's no real data monitoring/logging system; there are probably better systems out there to choose from. I'm looking to see whether I can get the GBLI5001 battery working with another inverter/charger with smart configurable features. (My inverter, SolarBright, only does PV panels to ac but it does log data and export them via WiFi which is useful/interesting). Also the GBLI5001 states 5kwh but only 4kwh is useable and max discharge is about 1.9kw. And the SP2000 is slow to react to new loads. For example if you boil the kettle the SP2000 wouldn't commit the necessary kw until the kettle has nearly boiled already. Also, by default, the SP2000 only allows discharge of the battery when there is no power from the PV panels. Apparently this can be changed to to forced discharge mode (to supplement PV power) via the archaic software, I never managed to get the software to work let alone change a setting! Anyway, there are probably much better systems to choose from out there. Enjoy your new world of solar panels, you'll love them.
