Huawei Luna Battery
The new Huawei LUNA2000-5/10/15-S0 solar storage battery looks very stylish.
We did our first Huawei Luna battery installations in August 2021.
They look very stylish. Waterfall inspired.
The chemistry, Lithium Iron (not ION) Phosphate chemistry. Very heavy, but very safe.
It only works with Huawei hybrid inverters, L1, M1, M0, maximum size 6kW.
Each battery module has 5kWh of maximum storage and can be discharged 100%.
(Which must mean that the actual storage inside must be a bit higher)
Each battery contains 8 temperature sensors (2 cells per sensor)
A self-deploying bag smothers the cells if any sensor detects a temperature over 170 deg C
A battery optimiser inside each battery allows new batteries to be mixed with old without power loss.
The optimiser also means that if a single cell fails in one battery module, the other batteries will carry on working normally.
If any of our customers with the earlier 'L' inverter which was designed for LG batteries, want to buy a 10kWh Luna (or larger) with backup, then we will swap their 'L' for a new L1 for free, thanks to an offer made to us by Huawei.
Each inverter can support 6 batteries (30kWh), and up to three inverters can be cascaded together to act as one, each with a battery to make a maximum 90kWh of storage.
10 year warranty
There's an optional back-up box for the L1 and M1 inverters only. It's job is to kick in (e.g. the inverter sends a signal to activate a relay) that islands the solar power flowing to the house (e.g. activates three contactors) so that all the battery and solar panel power flows to a dedicated 'essential loads' circuit.
5kW of continous power available with the L1 single phase inverter but only 3.3kW for three phase M1 inverters and no backup at all for the older M0 inverters. Single or three phase, it's a single phase circuit.
That's the bare bones of it.
Feel free to email me any questions.
In my opinion, this is a really good battery that is fully integrated with the Huawei inverters it works with
I installed one in my garage and I'm very comfortable with the safety features.
