Multiplus II 3000 12v with Honda 10eui

Hello, Can I use a EU10i 1000W 900W continuous with a Multiplus II 3000 230v ?
The generator has an output 900 watts therefore, an input limit of ~3.9 amps on the Multiplus II would be needed. Can the MP have a limit that low and what is the VA of the MP input. An input limit of 3 amps would fit perfectly.

The reason being I feel a small generator would be a better option than roof solar on a camper van. If your battery is low you either run the van engine or shore power. This I feel is were a small generator would be better and lighter to carry.

No, a 10 eu will not work with a mp 3000, the starting current will be too high.

I’d invest in solar and take the van’s alternator as backup

Only with ESS would you be able to set the ac current limit low enough.

Edit: I just realized that this is in a camper van and therefore mobile. ESS is not approved for mobile applications. There are several threads which go into the why that is.

Just take a separate charger for 12V with enough power and charge your 12V side without any problems … This leaves your AC In free for the shore connection and its settings. The generator with this low output would only ever be seen as an emergency solution …

Pretty close to the limit.
Not advisable.

Probably just have two 50 amp DC-DC converters if the alternator is up to it, rather than have 10% of a vans payload as a roof rack, solar panels and wiring. I really dislike the idea of solar on a van, when most of the time they’re of limited use and AC 230v power use is mainly in heavy in a small timescales. Solar would take a potentially a few days to recharge a depleted battery if parked up ‘offgrid’ for a few days - even worst in shade. Hence the idea of a small generator rather than run ~150 kW engine for 1-2 kW of charge, because when stopped the alternator runs a lot hotter without airflow from driving.

Just curious @thomasinaz why isn’t ESS approved for mobile use ?

I’d guess the Honda guzzles down more fuel then the vans engine in stationary…if its a diesel…

Because you can’t avoid having voltage at the plug when its disconnected from the grid.

Thanks Ludo, It’s not just the fuel it engine hours. I see what you mean with ESS the ‘prongs of death’ .

I get those standing on the road waiting to move 10ft forward, hasn’t killed my engine yet.

I guess it’s not a big issue but extra hours on the oil etc.

High temperatures and engine speed are a burden for your oil, the rest is easy.

One way to mitigate the ESS approved would be to have contactor / relay on the MP’s input with it’s coil on the shore power side. Then no power would come out of the input as the relay wouldn’t be energised via ESS only shore power.

Try to visualize your proposal, then come back.
