I’m curious as to why I’m seeing so many YouTube vids about this battery and why installers are keen to push it?

compared to a pw3 it has some advantages but for me not a clear winner by any means.

I’ve not come across this brand, but then again I don’t spend much time looking at batteries.

@simon-s is one of the top experts in batteries. What do you think Simon?

I've noticed lots of love for them on YouTube too - I wonder if it's slightly opportunistic due to the backlash against Elon / Tesla. I think a lot of people are now turned off the Tesla brand because of Elon's recent antics, and suppliers will not want to lose business of those potential customers who say they don't want Tesla.

Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.

It’s a really simple answer, GivEnergy.  

Installers and the market place got really used to the bargain that was GivEnergy.  

It’s all gone a bit sour with the support being so terrible and the attitude that the installer is always to blame.  We don’t actively sell it anymore either, which is a shame as the kit is actually not terrible. 

That’s left a big opening for a reasonably priced, easily scalable system.

Enter Sigenergy.  Super easy to install the majority of the time, half decent (not perfect) support and a user interface that looks good and functions well.  

Plenty of battery options, hybrid or string inverter setups, SP and TP installs pretty much identical.

A functional EV Charger helps a lot, and the new V2X is promising.  

Innovation seems key with Sigenergy, they’ve just released a micro inverter setup which integrates in the current system setups.

Then for the more techie prosumer, third party device integration is a doddle.

So they've filled a gap perfectly, with better kit and software.

It’s not the cheapest kit around, sits around the middle.  But its an easy sell and as installers, we have a lest a small amount of hope of support when it all goes wrong. 

Personally I like it, there’s a solid chance I’ll pull all the GivEnergy kit at my house and install the Sig with V2X charger.  It’ll work great with my BYD Seal 😃

@saenergy for me I feel the powerwall gives me for flexibility as it can change its inverter output without me having to buy another inverter. Also Teslas warranty seems more comprehensive. I don’t have an EV and looking at used Kona prices to get any decent range we would need a 64kw version, and my missus refuses to spend that sort of money, last car she bought cost £1k and nearly the same to get it sorted once we found what it needed, but still going 5 years on.

@adamk Tesla is a great option, it’s also one we install a lot of. 

Again, not perfect as there are limitations in scalability and control can be very limiting for more technical prosumers.  

these days they are a good value proposition and the ability to now install with the backup option, actually pushes them into the mainstream product price range.  

As for the EV, I’m a fan, been driving all electric since 2013 so lots of experience of all the pros and cons. 

We don’t buy cars as they dump value so fast.  Unless it’s the last car you intend to buy, it doesn’t make much sense for most.  Our latest is the BYD Seal.  Amazing bit of kit leased for just over £320 a month.  Our three year on cost is less than the expected depreciation so that works for me.  It also means there’s going to be some incredible machines on the second hand market for absolute bargain money.
