Living aboard means I'm obsessive about this stuff. On my LiFePO4 bank I actually back off absorption to 14.0V and skip it almost entirely — float disabled...
Worth noting that if you're building around a Cerbo GX anyway, you can just ditch the MPPT Control display entirely — the Cerbo's touchscreen (or the GX Touch 50/70) gives you everything the...
Been thinking about this a lot lately after seeing a few discussions elsewhere about ESS setups with the Multiplus II.
My current setup on the boat is fairly straightforward — Victron Multiplus-II...
Interesting project — though I'll flag that most of us here are UK-based so some of the specifics (grid tie regulations, net metering etc.) will differ from what you're dealing with in Ohio.
Good shout from @MarineGeoff on the temp compensation — that caught me out on my boat setup. I'd also add: check your absorption time settings in VictronConnect.
Been through this exact nightmare with a Honda EU22i that sat untouched from October to March.
First things first — the carburettor is almost certainly your culprit.
@HollyGaz worth checking which generation those Hotpoints are — the older drum motors with chunky permanent magnets are gold, but a lot of the newer direct-drive ones produce pretty low voltage at...
@Rob1963 living this on the boat — standing charge on my shore power connection is an absolute joke relative to what I actually pull from it.
Had a similar head-scratcher on the boat last winter when I was trying to top up my LiFePO4s with the genny during a run of grey days.
The Victron Multiplus was essentially sitting in the circuit...
Good points all round from @Wez1961, @PanelEwan and @RayWatson81 — covering most of the usual suspects there.
One thing I'd add from my own setup (lithium on a narrowboat): make sure you're using...
@Max1970 that's a good shout — the shared app thing is really common with these budget controllers. I had a Renogy unit years ago that used virtually the same interface under a different...
Good point from @Rob1963 on the ignition spike — worth adding that most combis also have a standby draw people forget about, typically 5-10W constantly just keeping the controls live.
On a 200Ah...
@MarineGeoff good shout flagging that — worth adding that the forecast feature pulls from a third-party irradiance API on Victron's backend, so when it breaks it tends to break for everyone...
Ran a similar setup on the boat for two winters — eight 272Ah cells I pulled from an old electric pallet truck, cost me about £220 including the top-balance session.
The BMS choice is where people...
@PartnerCamper winter on the cut is a different beast entirely. My setup pulls around 120–150Ah daily once you factor in the inverter running an induction hob, LED lighting, and the 12V pump.
