Hi Teams,

Thinking to get solar system installed for our home and would like to get your opinions on solar system choices.

I got a quote that a 8.82kw system for $35k+ inc gst (Auckland based). It comes with an Aplha Ess G3 5kw hybird inverter with 10.1kw battery, 21 x REC410TP5.

From the research I did, the Alpha ESS tech is quite promising but bit lack of quality/warranty/after sale support.

What brand would you go if looking for a solar system that has hybird inverter with battery?

Cheers

Hi - I have an AlphaESS hybrid system. Mine's the T10 3-phase 10kW system with 16.4kWh of battery storage. In general the system is working well, but there are niggles. Happy to share my thoughts.

The good:

Good pre-sales design (Solar Group)
Good installation and configuration of my backup circuits (Chris Stear, BoP/Waikato solar installer)
Good cloud data storage, web interface and smart phone app
User-accessible API available for smart home integration, but I haven't got round to it yet
Good integration with the ChargeHQ app for EV charging
System is working as designed and delivering results
Payback on investment is as expected (though not stellar).

The bad:

As an end user you do not have access to event logs. You can't see faults, and you don't even get notification of mains outage/restoration
Support is marginal at best. The local team are responsive, and I have a colleague whose system was replaced when faults became evident, but anything tricky goes off-shore to Australia or China, and there your results will vary. I'm still waiting for responses months after I logged issues
Downloading detailed stats from the cloud is marginal, especially for me with a 3-phase system. I cannot do this myself, and need to request the Solar Group support team to obtain 3-phase stats. Single phase should be better, but understand your requirements
The Alpha EV charger is 3-phase 11kW. If it had been a 22kW unit it would have been fine for my single phase 7kW EV, and integration into the inverter is good. But at 11kW it's not suited to most NZ EVs. I went with a 22kW Wallbox Pulsar Max which meets my requirements and integrates nicely with ChargeHQ.

All in all the good outweighs the bad, and I would likely choose the same system again, though I'd take a closer look at Fronius if there was a next time. If some features and post-sales support for AlphaESS systems were improved I'd give it a better rating.

Hope this helps.

Cheers - Steve
