Inverter advice for numpty …

[Grianan]

I could do with some really basic advice please.

We’ve just upgraded our leisure battery in our PVC to an under seat lithium 200 Ah.

We have 1 solar panel probably 120 Watts but not on documentation.

We have a B2B.

We upgraded to lithium to give us longer off grid shoulder season (Easter/October) as the fridge is only electric.

So I suppose the first question is does it look as if we have enough to allow for an inverter? And if so what size / type inverter.

The things that would make most difference are:

• my hair tool 700W
• recharging bike batteries whilst driving
• standard Remoska 400W

Any advice welcome even if it’s to do nothing.

Thanks

Hi Grianan , we have 200amp of NDS lithium with 150amp max, 60amp b2b and 120w solar along with an NDS 2000w pure sine wave inverter wired to all sockets in the van. We charge our e-bike batteries, use our coffee machine, induction hob, aircon etc as well as hair dryer and straighteners. Just back from 4 weeks in France, it’s transformational !

Our previous MoHo was a Campscout, which we kept for 3 years before part-exchanging for a new Adria in July last year.

Soon after buying our new Campscout, because of the compressor-only fridge, my Wife’s need for hair tongs and dryer, as well as charging e-Bikes and our wish to be off-grid for most of our travel, I upgraded the solar, installed 2 x 68 Ah lithium leisure batteries and a B2B. I wrote a fairly detailed report on this, which you may find helpful……

Good luck, whatever you decide to do. I am sure you will not regret adding a suitable inverter and gaining more flexibility for off-grid use.

Just had email reply from rhino installs saying inverter should be 2x capacity of maximum wattage item so at least 1400W. Before we call to chat through can anyone give simple explanation as to why? Thanks.

My 1000w renogy inverter happily works a 700w kettle…

Some electrical consumers(hair dryer) draw a higher current at start up which then settle down to their rated consumption.
The Renogy 1000w quoted above has a peak load of at least 1500w (maybe 2000) to cover the peak load situation.
It won't sustain that higher current for long before shutting down automatically.

So, we’re going with 1500W inverter, fitted by rhino installs at the beginning of September (lucky to get a cancellation) - in plenty of time for our next trip abroad in October.
