Called it at 17.2 kWh on the AC side.
If the two lowest cells had a bit more in them it might have pushed out to 18 kWh easy enough. Still, a useful amount of stored energy for a warm night.

Some progress to report on my home storage setup.
The patio is up, and after many tears and cuss words, painted.
According to AS5139, the battery must be at least 600 mm away from a window or doorway, so it will sit in front of the old chimberley stack.

The slab will easily support the B&R enclosure full of AVASS ex-bus cells, and power is taken from below the box. I'm using dual 32 mm conduit for the 48 V DC cables.
DC isolator and shunt trip will be mounted next to the PV isolator.
Also, I made a start on the conduit for the EV charge point. It's going to be supplied with 2C+E at 6 mm2 (32 A max) but I will probably tell the car to draw well less than that most days. The solar might only max out at about 5 kW in the middle of the day anyway.

Well done.

But with that size slab you only earned a stubby, not a slab .

As I always say whenever I do concreting work - You don't need to see my initials in it to know that my name is written all over the workmanship :lol:

Batons are up, which means the roof is next. I'll have to get the parapet flashing installed first though. Should be a fairly waterproof battery by then!

Where did you find the two Junsi loggers? I've been searching for a supplier for over 12mths with zero luck. The factory stopped making them over 2yrs ago and all my usual supply contacts have run out of stock.

From when I bought them about 4 years ago :) I have a BC168 balance charger I guard jealously too - can't buy them for love nor money. I bought my first one from @Hyena and the second one from eBay, but the first one eventually failed. I worked it bloody hard though.

Thanks for the offer Paul, but the BMS control boxes we make are designed around the functions of the Junsi cell log and its alarm feature. Looks like I'll be redesigning the whole set up to use a different cell monitor and I'll upgrade it to communicate via Bluetooth to a smart phone. The copy one that is near twice the size doesn't seem to work the same and its reliability leaves a lot to be desired.
