Couple of questions arising about our battery.
(now retrived van after over 100 days of lockdown from outside storage )
Battery is coming up to at least , 4 years old (wet lead)
Up until a 100watt solar panel was fitted, the CBE control panel showed 3 green lights (out of 4 ) dropping to 2 within 2 days off grid. Light use, led lights, water pump and drop down bed.
Solar panel installed just before lockdown, with victron blue solar mppt charger . Van not used in this period.
Just checked control panel, in the dark; showing 3 green lights. I had hoped it would be 4.
So is this normal , or a sign the battery is fading.?
In addition the green light on the victron was flashing all day , and was flashing before going into storage over 100 days ago.
The yellow light indicating float charge is on.
Victron manual says the flashing green light is indicating battery life charging is in place.
This is described as
Battery Life: intelligent battery management
When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months.
The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.
I don’t really understand this, but it seems to mean the green light should stop flashing after a few days. ?
or is it “normal“ for continuous flashing?
Any views, knowledge about this , would be much appreciated.
