Hello, I have a diy 1600W system on an isolated site that is running pretty well, but I am noticing that I have a constant discharge on the batteries of 0.5A, so 24W on my 48V system, even if my Victron app is showing a 1W AC Out consumption. I assume the loss is coming from the DC system but...

That's interesting. I am actually mounting my panel array on a pole, I haven't build the mount yet, maybe I could think of a system to have 1 panel facing South East, 2 panels South and 1 panel South West arranged around the pole. I could also arrange some at different angles, but that's maybe...

Exactly ?

That's how we note panel orientation in French, I guess it does not translate well internationaly. It just means the panels are oriented pure south.

Ok, so here's my final diagram: I'm gonna ditch the Lynx Distributor and do the DC distribution with 150A/70V Victron busbars and then use MIDI 40A/58V (Victron for 48V), so it should cover all my needs. Regarding wires, unfortunately the max wire size for the Multiplus is 13mm2 (AWG6) and...

Thanks guys, this is all so useful and so insightful. RMaddy I'm gonna write your name on the walls of the solar shed, you've been so helpful and nice ! Can't wait to start building :)

Yeah that is the issue I am facing... I guess I could remove the Lynx Distributor, switch to busbars and DC Breakers as Don suggested, as I should find smaller 48V Breakers... The choice of 48V isn't exactly a choice. I mean it helps that it'll allow me to grow much bigger in the future if I...

Ok, I'm back with a different plan! Very different, and way more expensive, but the talks on LFP made me change my mind! Let me know what you guys think! Wiring: Parts List: 2x Pylontech U3000C LFP Batteries 48V 3.55kW Lynx Distributor SCC MPPT 150 | 35 (Calculated here) Inverter Multiplus...

Yeah I just saw, that's too bad, might be problematic with the plan indeed !

Oh actually... The shop near me have these in stock... https://allo.solar/batterie-lithium-2-4kwh-us2000b-pylontech.html

Girona is actually very close from my place, you make me consider it ?

Thank you! Well, I wish I could go lfp... But I don't know if it's just around here, but right now in France the prices are: - 2x 12V 200Ah Gel = 660 Euros - 1x 24V 200Ah LFP = 4,000 Euros So the gap is a bit too big for me at the moment... Even for a longer lifespan and less backpain carrying...

Thank you very much! You rock :)

Cool, thanks, I guess I'll have to find room for a 6th panel :ROFLMAO: This is the ones I have right now: VoC 40.5 Vmp 32.5 Isc 10.3 Imp 9.85 At the shop near my place I see they have these panels available for 129 Euros each: VoC 40.6 Vmp 33.8 Isc 10.39 Imp 9.76 Those doesn't seem too far...

Got it, thanks! So how about 5x 330W panels, would that make sense? Although, I am not sure I can find the exact same pannels anymore, so even if they are 330W, I guess the VoC/Vmp/Isc would be slightly different... Is there a way to wire 5 panels, or maybe I should shoot for 6, but then I...

Many thanks for your very insightful inputs. Amazing! Here's my answer: Right, the issue I was facing with a smaller installation was several cloudy days in a row. I might think of upsizing the batteries then. So, I actually already own the two 330W panels, and since I wanted to reach 1400W...

Hello everyone, I finished sizing and planning a project for an off-grid location in the south of France (Hérault). I'd like your expert opinion and input on the sizing, wiring and hope everything is correct so I can start building! Sizing - Estimation : From that, I went with 1400W 24V...

Amazing, thank you so much, you guys rock!

Great, thank you! So do you guys think the single BMV-700 is enough/good to monitor the to groups?

Would the wiring look something like this?

Forgive me for my wording, English is not my mother tongue, and sorry for the confusion, yes I have a 24V system! Thank you very much for your advices. I am having troubles visualizing the wiring you propose. Do you have a diagram I could find somewhere online for this wiring? Roger! Yes that...

Hello, I am facing an issue and I can't seem to find a solution to. I was given a very simple solar kit including: - 1x Superwatt MPPT Inverter/Charge Controller 3KVA 25A - 2x 12V 100Ah Superwatt GEL Batteries - 2x 330W 24V panels It's been used only a couple of month in an off-grid location...
