My 'cheap' multimeter matched the mppt...

Hi Guys, Chinese diesel heater (display screen) wired direct to battery. EPever BN series 40 amp MT50 display monitor 3 month old Leoch AGM GEL 130ah battery (never dips below displayed 12.7v) 550 watts solar. Why the discrepancy in the voltage displays, and which is correct? Before you...

Guys, I have a Leoch 130ah AGM Gel battery... From a full charge I calculate that I use around 20/25 amps in an average evening. When I shut down for the night my MT50 still reads 12.7v which according to most charts I see still equates to 100%... I've also tested with a multimeter and the...

Hey guys, I'm in the UK and its pitch black right now. I'm parked under led street lights and It says I'm getting a trickle charge to my battery - is this a bonus or a false reading. Pic attached Epever BN series 40 amp, 550w solar. MT50. Thanks guys.

Doh, was the inline fuse from the battery.

Guys, just installed a single panel and scc. Assumed it was just turn on when I lastly plugged the mc4 connectors in at the panel end. Battery is at 12.75 v... Hope I'm just being stupid and it's something simple...

Is it better to wire my two 275w panels in series to double the voltage or parallel? I have an epever BN series 40 amp scc. I think I remember will saying it's better to have higher voltage for effiency?

Went for 12v in the end and bought a Epever BN-Series Tracer 40 amp MPPT... the one Will likes! Says maximus panel array of 525w and mine are 550w but I cant ever imagine them pumping out full cap here in the UK?

Cool man. This is going on my van. Think run at 24v is more efficient and just get a step down 12v? I'm in uk and our sunshine would hardly ever get panels to maximum effiency I guess. Attached a pic with the spec off the back if the panels. I can get lots of these brand new at dirt cheap.

Guys. I have 2 x 275w panels What size MPPT is best? It needs to be rated for 550w input right? Cheers

62v? Not what it says on back of panels?

£275 (around $350) for 4 panels.

Guys, I've been offered these panels at a crazy price. Pic below. Says the max effiency is 17.5% Is that good or bad? Jay.

Hi Guys, Been offered these panels, new at £95 (about $115). Do they look Ok. Half cells? Thanks Jay...

Hi Guys, These look pretty decent. Is there anything obvious I've missed? Cheers https://www.lifos.co.uk/products

The fridge will have a separate insulated and ventilated 'room' at the rear of the camper with a couple of PC fans creating air flow, so it is not in the same space that the heater is servicing. My understanding from wills videos is that 24v has less losses through the wiring and may (a little)...

The Waeco Dometic fridge is the 12v compressor: £860 (about 1000 bucks)...

Hi Guys, So I want to run a domestic fridge in my van through a 1200w pure sign inverter. I plan to have 2 x 100 amp hour lithium batteries wired at 24v to power the fridge and a separate 1 x100 amp hour battery at 12v to power smaller items. 2 x 200w panels will charge the 200ah bank 1 x...

I get it. Can you recommend a good PSW around 1000w that wont break the bank?

No good for a fridge then?

Guys, this inverter I’m looking says it can’t be connected whilst replenishing the batttery. Does that mean it can’t be on if the solar is charging the battery? Seems odd. Is this unit junk? I’ve been using the 300 watt version for 3 years trouble free but not whilst charging which is why I...

Forget both... save some extra cash, and go lithium. Last ten times as long used sensibly and wayyyy more useable amp hours.

Guys, In the video below, around 7:40, the guy shows off his custom wired charger so that he can use car chargers to power his leisure batteries. Is this safe/practical/legal? Also, am I late to the party - is this already on a shelf somewhere? You rock, Jay.

Interesting test results for the bigger CR115

Does seem very low to be true! I got the info from here https://www.jacksonsleisure.com/webasto/cruise/cr49/elegance/campervan/caravan/marine/fridge/ https://www.indelwebastomarine.com/int/products/fridges-freezers/cruise-marine-refrigerators/small-fridges-16-49-l/cruise-49-classic/

Guys, It says in their spec sheet that this fridge uses 265 (w/24) @5 degrees Celsius with an ambient temperature of 25 degrees C. So how may amp hours does that draw in a 24 hour period running on 12v DC? The calculator I just used says 22 ah in a 24 hour period. Is this correct? cheers.

Hi guys. Here is the video for the new KS Energy stress test. Let me know your thoughts. Again, I’m in no way connected with them!.. but i may want t Jay.

I saw a video on the Victron Energy YouTube channel where they showed alternators burning out when charging lithium at low speeds due to the high draw but low cooling effect from the internal alternator fan. If I run a split charge via the van lead acid battery I assume the internal resistance...

Hi guys, I ran a post a couple weeks ago asking about this new battery supplier. They've just uploaded a strip down video. Please tell me what you think. I'd love a battleborn but not available in UK! Also, post a comment on his video. This may help future improvements?

Hi. Based on the cotswolds. Currently holed up in Leeds.

I took some screens hots of the internals from their website...

From digging around I see that the guy behind the company is an electrical engineering who has come out of retirement to set the company up. Also has an RV!

Hey guys, I've been looking to buy a battleborn in the UK but we don't have a distributor here yet. Tonight, I came across these start up guys. Looks like cool product. Love the 300ah unit! Please have a look at the specs, I'm thinking of buying one but there might be something I've missed...

Hi Guys, Is this battery reviewed anywhere here? Cheers, Jay. https://www.ebay.co.uk/itm/100Ah-12V-LITHIUM-LiFePO4-Battery-for-Leisure-Solar-Wind-and-Off-grid-12-volt/131402654613?epid=15033526929&_trkparms=ispr%3D1&hash=item1e98356395:g:YpUAAOSwB-1Y3jQC
