Bit of a different angle on this one, but it got me thinking about when I first got my tiny house setup running and how much I'd have valued someone local who actually knew what they were doing with generator integration.
If anyone's in a similar boat — trying to get a diesel genny playing nicely with a battery bank — the key thing I'd say is don't underestimate the charging profile mismatch. Most generators just chuck out raw AC and your inverter-charger needs to be set up correctly to handle it, otherwise you're either undercharging or potentially damaging cells.
On my setup I'm running a Victron MultiPlus which handles the generator input really elegantly — you can set the current limit so the genny isn't constantly hunting or overloading. Took me a fair bit of reading the Victron forums to get it dialled in properly, mind.
For anyone genuinely needing hands-on help with this kind of thing in their area:
- Local Victron installers (check the Victron dealer locator) are often surprisingly helpful even for partial jobs
- Some narrowboat and off-grid Facebook groups have members who'll help for a modest fee or even just a cuppa
- offgrid4less members — worth posting your county, someone might be nearby
The generator-to-battery piece is probably the trickiest bit of an off-grid system to get right remotely, because so much depends on the specific genny's output quality and your battery chemistry.
Anyone else had to help a neighbour or newcomer get their generator charging sorted? Curious whether others have found good local networks for this kind of practical assistance.
