Old ELF setup
Fri 7th I connected one panel, via the Steca Controller, to one old battery. Used it as load battery and measure a use of 10Ah total.
Could see from the Steca the Asus 900 uses 1 amp
Sat 8th Since then I have 2 old 50w panels connected via the Steca to one old battery. The other old battery I have topped up with water, which was a bit iffy as it was a sealed battery. The six cells needed about a litre so hardly surprising it/they were almost unrechargeable.
That battery as end of day on the 9th was rated as 52% charged, by the next morning is was 48%
Switched old battery. Bat I received 25Ah charge via Steca and was at 80% when disconnected.
Connected two old panels and one new REC max charge rate was 4.4 of 6.8 generated? Will fill with water tomorrow.
Bat 2, filled with water 2 week ago, was at 3% charged at connect. It rose to 12% at sunset, 15% by 2100 hours and 18% now at midnight. 19% at 0100 How ??????
At 0900 theSoC reads 23%??? and now at 1200 the sun is up but it is overcast 0.6A charge, 12.8v Soc 25%
Tue 2nd Dec 1140 Soc 54%
Jan 1st 2015 Soc 61% however the battery seems to be discharging quite rapidly down from 80% two days ago. I should check there are blocking diodes in the each of the two panels.
