SolarEdge Solar inverter and battery review- Updated December 2021


SolarEdge have a new range of products...and they look good.

Single phase products replacing the older HD Wave and Storedge are the fully featured Energy Hub and the defeatured Genesis.
For the extra $400 it costs to get Energy Hub over Genesis I'd say get Energy Hub because you'll end up paying a lot more with all the extras you add on over time to the Genesis.

The whole point with SolarEdge has always been full-featured, so go Energy Hub.

SolarEdge now have their own solar panels, 370W at the moment, with a SolarEdge optimiser factory pre-fitted and a nice 25 year warranty.
They have their own battery and back-up box too, so whilst this is all made in China, it's NOT a Chinese company (Israeli) and that matters to many people.
The main point though is that you can get everything from one manufacturer.

The single phase Energy Hub (I'm not going to even discuss Genesis from now on), comes as a 3kW, 5kW, 6kW and soon 8kW and 10kW.

It has a built in consumption meter so all we need to do is run a cable for the CT around your main input cable, so if your space in the switchboard is tight, that's great.

In a year or two there will be an EV charger. It won't be DC connected though, just a normal AC charger that gets its power after the solar has been converted to AC so just another household load and not a big deal.

The latest new development from SolarEdge is their 10kWh battery, the Energy Bank. A maximum of 3 batteries can be connected (2 in parallel, the last in series) to each inverter.
It's a great move that others like Huawei and Sungrow have done. Integration and future-proofing is much better when inverter and battery manufacturer are the same.
It's a fully DC coupled solution meaning the Energy Hub inverter can simultaneously draw panel power for household loads and export and the same again for charging the battery. SolarEdge allow 200% oversizing when their battery is connected, so 10kW of panels on a 5kW inverter.
There's some talk that SolarEdge will allow more oversizing than this, but frankly, I can't see much point. 200% is plenty.
In some ways SolarEdge and oversizing are a bit of a headache for STCs subsidy claims for installers, because when the battery is connected another SolarEdge interface is needed (replacing the old SESTI box) called the 'DC Combiner box' that sits between the solar panels, battery and the inverter so the panels aren't connected directly with the inverter anymore. It becomes a 'multiple mode STC claim' but in the end, as far as you are concerned, the subsidy will be paid.

The battery charge/discharge rate is 5kW and there is a separate back-up box for when the grid goes down that can handle the input of 3 inverters up to 100A which is unusual for sure.
The battery is wall-mounted as standard, but a floor mount kit is available for a small extra charge.

One nice feature that we already saw with Huawei and their self-deploying 'fire bag', is a fire extinguisher in each SolarEdge battery. Safety is the name of the game with big batteries in the family home.

The warranty on the batteries is the usual ten years but a more realistic degredation rate of 30% over that time. Others have offered warranties of 40% which is far too conservative for LFP cells based on what I have read. (20% is more realistic).
The usable power from each SolarEdge battery is 9.7kWh, not the full 10kWh though, so that might explain the slightly more generous warranty condition.
I'll add to this review shortly with pricing and pictures, and also review the SolarEdge 3 phase hybrid.

Footnote added 19th Jan 2022.
The SolarEdge battery is due in Perth late March 2022 and will be only for the Energy Hub single phase inverter to start with.
Apparently 'the battery doesn't work with the new 3 phase hybrid yet'. Working on it apparently.
Pricing on the battery won't be locked in until March but our wholesalers tell us that it will be $11,500 to $12,000 for each 10kWh battery and that doesn't include install.
Compare that to Sungrow's 9.6kWh at $6,800 ex install and Huawei 10kWh at $8,400 makes SolarEdge pretty pricey, and frankly they aren't using the safest chemistry either.
Underwhelmed is my view, but like Fronius, reputation alone will keep the sales rolling in, because the brands are so solid.
