Unfortunately leisure battery at 5 years has given up the ghost.
Now looking at the options for replacement: -
1. Stright replacement Lead Acid, look at increasing to 130Ah.
2. Fit an equivalent GEL battery.
3. Change to Lithium with all that involves.
Questions for the knowledgeable amongst us, please.
Option 1) is it a case of simply purchasing a 130Ah and dropping it in.
Option 2) As 1 above and simply switching the Nordi charger from Lead Acid to GEL setting. Would I need to do anything with the existing MPPT SUN solar controller.
Option 3) EcoTree have an offer on a 100Ah lithium battery at £250 which brings lithium into scope. This is where advise will be greatly appreciated. Here goes: A). can you get a lithium battery with traditional post connectors (the ones I’ve seen have screws to hold the cable). B). Will I need to change the existing MPPT solar controller.
C). Will I need to increase/change the existing 120amp solar panel up on the roof.
D). Will the current charger, charge lithium even though it doesn’t have a lithium
setting.
E). Subject to answers to B & D above is there a basic package of items required when changing from Lead Acid to Lithium.
Useful info. We spend approximately 2 weeks off grid at a time. Probably 10-15 times a year. We like to watch 2 - 3 hours TV on most days. We run fridge/frezzer, hot water and heating if required on gas.
