PW3, Givenergy AIO, or Enphase solar & battery system?
Hi All, new to the group. We’ve received 5 quotes for solar panels and battery systems and have pretty much decided go with Aiko panels (16 x 485W) but aren’t sure which battery system to go with.
Most quotes have offered the Tesla Powerwall 3 as an option but I’m also considering Givenergy all in one. The installer has recommended Tesla and Enphase (very highly) over Givenergy but the generation estimates in their quote indicate the lowest for Enphase and it’s the most expensive so we’ve almost ruled it out.
Givenergy is the lowest price (nearly £2k less) with the same battery size as the PW3 but they are offering the 3.6kw Aio inverter which is of course lower than the Tesla. I’ve seen several posts on the PW3 but any experiences with the Givenergy Aio? Any recommendations or advice on which system to go with would be greatly appreciated. Our current consumption is around 2700 kwh but we’re also getting a hear pump soon so would like to go with a big enough battery. Thanks in advance!

Considered or has quotes for Sigenergy? Very good kit and easily expandable
-
none of them offer Sigenergy and we’ve been reading good things about it too. Do you know of any installers that do?
-
It will depend on your location. Have a search online for installers in your area, check their social pages and website to see if they install Sigenergy.

I don’t know anyone that regrets fitting a Powerwall. Ask for whole home off grid capability too. The inverter in the PW3 will ensure battery charges quickly and can supply all your home in all weathers. The user experience is both simple and powerful.

Recent reports of GE customer support have not been complementary
Might be worth some research

I’ve been successfully running my Givenergy system for 5 years but it isn’t an all in one and I have heard lots of complaints about it on the owners group. I’ve also been running a Sigenery system for the last year and it has been faultless. It has the advantage of being upgradable which my Givenergu system isn’t. Of the two I prefer the Sig
Enphase micro inverters are only worthwhile if you have panels in more than two orientations , otherwise a total waste of money. And you have the issue of electronics up on the roof with access costs should you have a problem

The inverter at 3.6 is far too small especially if you are adding in a heat pump.
You would be wanting the biggest inverter option possible to pull energy from the panels and battery to cover the house demand. With a smaller inverter you’ll then be forced to go back into the grid connection to top up what the inverter can’t provide.
Very rarely hear of any complaints following a Tesla instal, yes it’s a premium product and pricing but with all renewable product, you get what you pay for.

As said Sigenergy. 1 powerwall would not be enough for a heat pump to run off batteries
3.6kw inverter was the norm 3 years ago
-
Im waiting for a sigenergy install. 12 panels, 6Kw inverter, 27.12kwh battery storage for around 12k

I can’t comment on the hardware I chose Fox over Givenergy. 3.6kW inverter would be too low in my view if you have electric oven and hob plus other appliances. I have 6 for my 6.1 kW array. Allows me to use multiple kitchen appliances at once

We got a Powerwall 3 in November and not regretted it so far. We’re an all electric house with a heatpump. On the very coldest day it’s depleted by lunchtime but most days it seems to be lasting well into the evening. I considered an expansion but I didn’t think the payback was there, you want to be depleting it as regularly as possible for the business case
I’d considered Givenergy years ago but after initial positives they seemed to start getting some flack particularly for the first AIO
As people have said I have heard good things about Sigenergy. I debated between that and the PW. In the end I went with the PW as it was a bit cheaper, more established and I had a Tesla already so went with the ecosystem

Why would you consider spending all that money and installing GivEnergy its very poor customer service and the inverter is far too small the minute you put your kettle on (3kW) youll be pulling from the grid you want a minimum of a 6kW but id say for the price difference put an 8kW on to future proof, the Giv AIO has too many issues to even list, stay away from it, tesla is good, enphase is okay but I wouldn’t go with it, my preference would be SigEnergy its very very good kit and should be same price as Tesla, what I like about it over Tesla is, its modular and stackable so adding to it is easier, cheaper and takes alot less space, Tesla dont tend to make the new stuff they introduce compatible with the old so in a few years if you decide to add a battery you may not be able to, which alot of people who had the Tesla pw2 are finding now (we cant get them anymore) and pw2 is not compatible with pw3, ask for a Sigenergy quote
-
At the very least they should be quoting you the GIV AIO with the 6kW inverter
-
I’d personally go with Tesla Powerwall 3 if you can afford it — the higher inverter output will suit a future heat pump better. GivEnergy AIO is good value but the 3.6 kW limit might feel restrictive later. Enphase Energy is great quality, just pricey unless you need microinverters.
