If I have a 48v battery that quotes it's capacity as 3.5Kwh, can I calculate the (approx) Amp Hours as 3500 watts divided by 48v which gives 72.9 amp hours?

I have an "off grid" setup which uses a 48v MultiPLus II, Cerbo GX, a couple of MPPT Charge controllers and a 48v LiFEPO4 battery..so far so good. I'm trying to find out if I can utilise the "AC In" on the MultiPlus II to charge my battery during a specific time window each day (at night when...

I'm looking to buy a 12v 100a LifePO4 battery in the UK but am struggling to find any "local" suppliers that have AOLithium, Chins or SOK available. Do any of you guys know of a supplier in the UK or do they all have to come from Europe, China or the US at the moment?

I've just installed my 150/35 Victron charge controller and connected it to the DC breaker from my PV panels, but I don't yet have a battery (having trouble sourcing a LifePO4 in the UK) and wanted to know if the controller will let me configure it from the power supplied by the PV's alone or if...

I currently have 3 x 415W panels in series but have a couple of older 330W panels that I wanted to try and add to the existing setup. I was wondering if the configuration in the diagram below would work without causing any damage to the panels, even though the overall output would be reduced?

I'm trying to purchase a 48v LiFePO4 battery in the UK but all the suppliers seem to be "out of Stock" until July or later.....presumably this is a wider issue of not being able to get the components from China?

I'm planning to try and power a domestic washing machine from a 12v LiFePO4 battery with a 3Kwh inverter (UK - 230v) and have done some maths but wanted to make sure I'm heading in the right direction. I've been monitoring the washing machine (running from a normal 230v outlet) over a period of...

I'm keen to install a 3.6Kw Hybrid solution with PV initially and then add a battery at a later date. I'm quite comfortable with all the installation work and will ask a friendly, qualified sparky to validate my work and make the final connection to the consumer unit. I was looking at the...

I'm considering installing a MultiPlus at home to power a dedicated circuit that isn't connected to the "grid" but I know the PV won't be able to fully charge the battery for obvious reasons. I was hoping to be able to connect the MultiPlus AC-In to a normal power outlet (as per any other...

I've currently got a couple of 330w (40v 10a) panels connected in series but the battery I'm looking at (LiFEPO4) has a recommended charge current of 20a, which is double what my panels can currently manage (unless I configure them in parallel). Can I safely charge the battery at 10a (via a...
