Electricity - Advice On This Spec Please?

[Oldrat]

I’m just getting quotes for my new LWB Crafter conversion.

My request was for an electrical system capable of 4 days off grid.
We’re expecting to run a gas and electric Truma 4e water and heating system,
A 90l thetford compressor fridge along with the usual sundry devices- phone chargers interior LED lights etc.
So not too great a demand.
(microwave /tv on hook up and a gas grill/oven)

My builder has suggested this set up...

12v 230v electrical system comprising off
votronic vbcs 45/30/350 ( b2b charger,solar mppt controller.230v charger ) inc votronic jupitor display/control panel,water tank probes.fuse panel
250 watt glass monocrystalline solar panel

transporter energy 100AH 12V LIFEPO4 DEEPCYCLE BATTERY
Or a cheaper option
1x 110amh gel batt


Poss upgrade to 60 amp b2b chargers

OR
A cheaper option..
nds gold 30 amp/cbe 210 control panal b2b,mains charger,mppt solar controller
Possible upgrade to nds 40 amp

As a ‘lecky numpty I humbly seek the advice of the techies on here.

What’s your thoughts on the system and its options please

And

Any thoughts on roughly how much would I expect to pay supplied and fitted would be a real bonus


Grateful as ever

That votronic unit ticks all the boxes but a tad expensive, but as you say the LIFEPO4 will also be expensive so if you also have the solar, why not just go for the AGM battery? you can always swap the battery to LIFEPO4 in a year or two when the prices drop.

See this thread Votronic Dc-dc Battery Charger - Compact Design

Thanks Loz
I’m already baulking at the cost of lithium so will be looking at AGM.

I hope that you don’t mind a couple of Qs

Following Greg Virgo’s Mercedes Sprinter build, led me to this AGM battery at £179 from Apha batteries.

Is it any good or would you be able to recommend a quality AGM

Also
What would be the benefit in choosing the suggested 60 amp B2B charger at an additional £150?

Cheers, I really appreciate the advice
