300w Solar And Camper Electric Set-up

[Dellmassive]

Thanks - maybe back to this thread? 300w Solar And Camper Electric Set-up

---

have priced things up at around £2.6k (assume i do not need the redarc mppt as the other bits cover that off?)

300W SEMI-FLEXIBLE SOLAR PANEL - £599 12V solar panels charging kits for caravans, motorhomes, boats, yachts, marine

Victron Energy LiFePO4 Battery 12.8V/200Ah Smart BAT512120410 - £1389 Victron Energy LiFePO4 Battery 12.8V/200Ah Smart BAT512120410

Victron Energy Phoenix Inverter 12/800 230V VE.Direct UK & Bluetooth Dongle - £317.1 Victron Energy Phoenix Inverter 12/800 230V VE.Direct UK & Bluetooth Dongle

Victron Energy Smart Solar MPPT 75/15 - SCC075015060R - £106.41 Victron Energy Smart Solar MPPT 75/15 - SCC075015060R

Victron Blue Smart IP22 Bluetooth Battery Charger - 12V 15A, 3 output - £153.3 Victron Blue Smart IP22 Bluetooth Battery Charger - 12V 15A, 3 output

Victron Energy Smart Battery Protect 12/24V 100A - BPR110022000 - £72.8 Victron Energy Smart Battery Protect 12/24V 100A - BPR110022000

Total - £2,637.61 (plus install and sundries)

The only issue is the peak wattage on the inverter, i guess i would need a bigger one for what i mentioned i would like to achieve in the other thread...

hmmmmm... what to do....

The Redarc is a DC-DC charger, that also has a built in MPPT.
(without it you will only have solar or EHU - so a DC-DC is a must)


EHU - charges from 240v when hooked up
Solar MPPT - charges from sun when its out
DC-DC - charges from alternator when driving


I run the Redarc DC-DC, but, even though it has its own built in MPPT function - i dont use it.

I much prefer to use a separate Victron MPPT for all the functions you get with Victron.


so id say, you need a DC-DC charger especially is you are running a lithium.

My reasons for this consideration is the life of the battery and the fact that the batteries are more resilient. Potential advantages for me would be the ability to have an induction hob, possible microwave use off grid and a faster more reliable charge. As well as possibly running my 1700W coffee maker... Would that be possible with the victron batteries?

right going from this:

look at getting a decent 2000W or 3000W inverter (maybe look at Cotek brand) (more power to run coffee machine)

look at upgrading the Victron Energy Smart Solar MPPT 75/15 for a 100/20 (20A - faster recharge)

Look at upgrading to Victron Blue Smart IP22 Bluetooth Battery Charger - 12V 30A, 3 output (30A - faster recharge)

or another option is to just take a 2kw suitcase generator for the few occasions when you need to draw large loads.

remember every 1000W will draw 100A of power from the battery . . . . . . . . you start to need massive thick cables to handle the current. (around 1500W avaerage up its worth looking into 24vDC or 48vdc systems as the current load drops back down) (but the occasional 1500/1700w is ok for 12v systems provided you rate everything for those loads)

Thanks @Dellmassive. thats everything from me on this. Just need to see if a. i can afford it and b. will it not all take up too much space.

Hi @Dellmassive,

Have been working with my converter on the solar set-up -would be great to get your thoughts on the suggested components. Cheers.

Do you really need a hook up and solar? With a 200ah lithium battery and a good 50v dcdc charger you can be off grid for a while with only minimum driving time. You'll save a whole lot of money and even have enough to upgrade to 300ah lithium?!!!! Keep it simple?

It's a fair point but would like to maintain maximum options and the solar will allow us to effectively free camp or not to have to worry if we miss the EHUs...
