Battery Installation

The batteries arrived today with the MPPT and have been installed. It was late in the day before I had finshed and initially the controller went to bulk then abs.

The first thing I did was to make a stainless steel backplate to fasten the controller to and use copper and plastic tubing to keep it off the wall, only a centimetere or so.

I have also connected the 1200w inverter, but there is no other loading.

May 7th Battery voltage of the 2 x S6 145's in series was 12.76. The electrolyte was high in one cell so I distributed it amongst all six.

Cable from MPPT to batteries is approx AWG 8 or 8.4㎜² (50 amps)

Could do with
See https://www.altecautomotive.co.uk/25mm2--4-awg-automotive-cable-17000amp-2040watts-rated-various-colours-available-375-p.asp

May 9th Electrolyte levels are fine

Measured the SG.

May 13th Must use VE Direct USB to set up MPPT and equalise. ✓

June 17thHave fitted a fuse box to inverter output and wiring from there to a) 6A fuse to wiring for sockets to a double socket about the workbench, a double socket by the computer platform and wire to a further socket by the mezzanine ladder. b) 16A fuse for cable to external socket and c) Unfused to a 3 gang row above the electric work bench.

So for power to any 1) switch on inverter, 2) switch on fuse box.

I will not be making a spreadsheet of input and output for a while.
