Huawei Solar Inverter Review Australia 2018

Maybe we have been doing this too long, but it seems like years since any solar product came along that could remotely be termed a game changer. Enphase were pretty cool before SolarEdge out cooled them, and now in 2018 Huawei have got our juices flowing again. This product is simply exactly what people want.

1. It's a hybrid inverter. In-built battery charging and discharging hardware and software. Fronius costs at least $1700 more for a battery interface as do 90% of other inverters.

 

Left Fronius. No battery connection there. Right Huawei with + and - connectors for batteries

2. It's a bit cheaper than the non hybrid Fronius Primo.

3. It has a genuine 10 year product warranty + 5 year labour warranty from the 83rd largest company in the World as measured by the Fortune 500 list (Last year sales were US$75 billion). Huawei are also the World No.1 commercial three phase solar inverter manufacturer, the World No.2 smartphone manufacturer, ahead of Apple, behind Samsung and more than half the World internet and phone traffic is carried over Huawei routers and telco switching gear. Huawei are 100% owned by their staff which is not only bizarre for a company of this size, but is also actually pretty excellent too. Pride in your work = Better annual dividend. Nice.

4. It's tiny. Half the size on your wall compared to a normal 5kW inverter like Fronius Primo.

5. It's beautiful. Won a prestigious international design award.

6. It has optional DC optimisers ($80 each) that can be connected to all or any of your solar panels. Huawei are unique with their optimiser design. Instead of having an optimiser on every panel (e.g. SolarEdge or Enphase micros) you only fit them to where you need them. This hugely helps us design a very cost and power efficient solar installation. For instance, we can create a 14 panel string, with 10 panels facing North and 4 facing West and put optimisers only on the 4 West facing panels with no power losses. Or we can put optimisers on a couple of panels that get shaded now and again and again, with no loss of power to the rest of the string. (More on that at the bottom of the page).

7. It's very safe and a bit geeky too. If you buy the optional smart safety box ($300) then any panels with optimisers will be instantly de-energised if you choose to flick the switch or AC power is lost. An added benefit of the smart safety box is panel level monitoring so you can see the individual output of any panel that has an optimiser attached. This strange looking device has successfully finished testing and first shipments arrive in September.

8. The Huawei NetEco smartphone and web based reporting is excellent. Most people will see what they need straight away, but you can delve deeper if you need to. Huawei tell us that they are in the process of upgrading the software to accomodate the new features (e.g. panel level monitoring) before the first Smart Safety boxes arrive in September. If you fit the Huawei smart meter, even without batteries, then the NetEco software will show you your consumption and exports, (Same as Fronius and SolarEdge smart meters) but its real purpose is to manage the store or release of battery power based on your immeadiate home power use.

9. The Huawei FusionHome is ready to go with the LG Chem high voltage batteries. Just connect the smart meter across your phase cable and off you go.

10. An easily Googled review by a Queensland solar company on the Huawei hybrid had so many errors in it, we feel the need to correct them lest you believe the rubbish written. Yes, panel level reporting works. Yes, you CAN connect more than 11 panels on a string and still safely connect to the LG battery. This was very mischievous reporting in the review because they KNEW that the 500V input limitation was the LG battery and had nothing to do with the Huawei inverter...YES, backup during power cuts will be available (early 2019) and so on. The panel max thing we explain in more detail on our FAQ page called "Strings Volts Amps and Watts" about half way down.

11. The current models are all single phase, but the three phase hybrid model(s) are due Oct/Nov 2018. For now, installing a combination of single phase inverters will work just fine (e.g. 3kW+2kW)

Note. For larger 3 phase non hybrid installations the Huawei Fusion Solar inverters (8kW, 12kW, 17kW, 20kW and 33kW) inverters are available. They are really excellent, World leading in fact, but an entirely different technology to these FusionHome residential inverters.

Options
Hauwei DC optimisers are $80 each installed. You can have as few as one optimiser if you are combatting shade, or optimisers on every panel if you want multiple roof orientations or panel level monitoring. Very flexible and cost effective.

Compatible batteries.
The Huawei inverter currently only connects to the LG Chem RESU 7H and 10H high voltage (400V) solar storage batteries. The 10H currently costs $7,500
