Second system build this week!
This one is a based on a multiplus 2 24/3000 GX with victron battery protect/Orion dropper combo for 12v supply, smart solar 150-35, fogstar drift 24v 280ah and solar array supplied by customer. Made a cool busbar/smart shunt thing by accident which I quite like.
And of course bimble sent me some sweets, how nice!
To be installed next week, near Penrith.

Here's a nice medium sized system I recently built, didn't get any photos of the array sadly, this setup is cool because once the batteries are full, it charges an electric car.
Specs: 4kw PV, 5kva victron multiplus 2 GX, 70A victron smartsolar, 16.2Kw gobel power lifepo4 battery (314ah MB31 cells 16s ( 51v), JK bms).
Using something like this makes you realise how huge electric vehicle batteries are compared to those typically used for off grid houses!
I build off grid systems to order, get in touch of you need a quote or a chat!

Pleased with this smart little array I built this week in the central belt. 3 x hyundai 410w panels. Hot dip galv Unistrut in concrete.
Supplying power to a hut with fogstar drift 12v 608ah battery, victron multiplus 12-1600-70 via victron smart solar 150-70 with display.
Get in touch if u need something similar (or bigger/smaller!).

In the workshop today... more blue boxes and complicated off grid nonsense. Going to install this lovely lot in a house north of Newton Stewart in the middle of nowhere next week. Going to be a bit of a diesel/solar hybrid system as it's a house which is entirely electrically powered... heating, shower, borehole, cooker the lot.

Small but perfectly formed install for off grid holiday static.
Includes generator hookup and 35A charging via inverter/charger. Using the incredibly sexy fogstar drift pro battery - maybe the best money can buy?

Specs:
405w recom panther PV panel on custom made hot dipped galvanised steel frame.
230Ah 12v fogstar drift pro lithium LiFePo4 battery
Victron multiplus 12-800-35 inverter/charger
Victron smartsolar 12-20 solar regulator
Nice!

This exact spec installed within about 100 miles of Galloway would cost you around £2500 fully up and running with a year free service callouts. Battery warranty 10 years, victron warranty 5 years.

Get in touch for your off grid power needs, I have experience of a wide range of sized systems. Scotland and northern England mostly but will consider anywhere!

Starting to get alarmingly complicated...! Nearly time to fire up the panels and see if it works!

Latest job finished off today, in sunny West Kilbride. Installed in a very well engineered new build hut, with amazing views out over the firth of Clyde and the mountains of Arran.

Specs as follows:
1230w of Canadian solar PV panels
Victron multiplus 2 48v 5000VA inverter/charger
Victron smartsolar 150 35A solar controller
Victron smart shunt battery monitor also providing mid point monitoring.
2 x fogstar drift 24v 230ah LiFePo4 batteries wired in series to 48v

Always a bit nerve wracking to be installing in a building constructed by and belonging to a tradesman who clearly knows his stuff, and a relief to find he thinks I've done a great job!

If you are needing an off-grid power solution anywhere in Scotland or Northern England give me a shout...

Here is last week's galloway off grid job... possibly the most awkward I've ever done! A lot of kit fitted into a small space.
Also easily the most insane medium wheelbase 4x4 sprinter power station I've ever seen let alone installed!
Commissioned by my friend Orc to improve his winter lifestyle (he lives in here full time) and provide power for crew at festivals.

Rig consists of:
1230w Canadian solar pv array, running at around 100vdc.
Victron smart solar 35 amp mppt charge controller
Victron multiplus 2 3000VA inverter charger, connected to hookup.
48v 280Ah LiFePo4 grade A EVE cell battery bank with JBD bms (over 15kwh inside sprinter passenger seat!)
Victron Orion 48v-12v 30A dropper to provide 12v for domestic loads.
Victron cerbo to handle communication
Victron touch 50 interface screen so we can see what's going on!
30A 12v charger to charge starter battery if needed.

And it all fits in the cab, inside the passenger seat, on the bulkhead and in the footwell.

The icing on the cake is that all he has to do if he has any issues is turn on his Wi-Fi hotspot and I can remote diagnose the system or alter settings thanks to the cerbo! Such a useful feature.

The last photo is a "before" photo of the rig i was replacing.

I can build systems of any size within reason, mobile or static. Get in touch if you have any questions or are interested in a quote.
