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 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 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 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?

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'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'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 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...

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'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...
