Hey all,
Looking for some advice. So I've had the same set of lead acid batteries for about 7 years now and they've basically given up the ghost. And while my boat was in the boat yard getting painted, the inverter went arse up due to being filled with sandblasting sand. So between the two, it's got me thinking about my electrics. Honestly, I don't use a lot of electrical items on the boat outside the lights, fridge, pump for shower, pump for water, bilge pump. Anything like running a laptop, TV etc. I just run off the built in battery (laptop/phone) and the TV is rarely turned on. In fact, I'm pretty sure it's also full of sand and knackered. So I'm beginning to wonder if replacing all the 4 lead acid domestic batteries and getting another inverter would be a waste of money?
What I'm wondering is how few domestic batteries I can get away with installing to run the pumps, lights and fridge. 1 would be ideal but I suspect that might not be possible. Lights and pumps fine - fridge as well? Possibly not. I've also got 600w of solar on the roof. The fridge is one of those Inlander 12v conversions.
For the money I'd spend on 4 batteries and another inverter, I could get one or two domestic batteries and one of those big Bluetti power stations (https://bluettipower.co.uk/products/bluetti-ac200max) for running any 240v stuff on the rare occasion 240v stuff gets run.
Wondered if anyone has any advice/suggestions? What is a realistic minimum based on the above?
Just thinking, I'd probably need an inverter of some kind to charge up the Bluetti. But maybe just a cheap and cheerful one rather than a fancy Victron one.
Cheers!
