Sounds very interesting but I don't really follow what you mean. Could you add some link and/or a photo to help me understand? Thanks!

Hi, I would like to clamp my panels along the long module side as described in the Meyer burger panel installation guide. Maybe just on square metal bars? (not necessarily) What clamps could be suitable for this? In my mind I imagined some kind of C style clamp like below. But I can't find...

After having contacted a couple of vendors, as well as Victron themselves. This is the somewhat confusing information I got. Below is reply from Victron's sales dept. I couldn't find a way to get in direct contact with the tech dept. From a Vendor, even after I showed him the above reply from...

I linked the Victron MPPT calc for Meyer Burger Black 380W in my previous post, here again. It's the one that is just 0.1A Impp away from removing my SCC from the suggested compatible products. Feel free to tinker around with it :) Not sure what you mean by allowed ratio? Thank you for your...

Thank you for the feedback. Interesting this thing that fuses have a 1.56x Isc rating. I've send the question to Victron, I'll let you know if I get a reply. But for now I just realized how to use the Victron MPPT Calculator properly. It seems they will suggest my product as long as Impp < 20...

@MisterSandals Yes, i like to be thorough. No worries, but I didn't calculate this to ensure I'm not breaking reverse polarity. It was to explore what is an appropriate panel Isc to avoid breaking the limits of my charge controller under operation.

Yes the quotes above are straight from the manual. From what I've learned and understand so far Isc increases just slightly with temperature. For example for the luxor panel: Isc_stc = 13.6 A T_stc = 25 °C T_max = [Central Italy] = 75 °C Tk_i = 0.049 %/°C Isc_max = Isc_stc * (1 + Tk_i/100 *...

But do you guys think I can safely go ahead and use panels with 27.5 A at STC then? Or do I have to consider this possibility of rare irradiance events as mentioned by @sunshine_eggo? I don't really understand the thing you said about "operating well under Vmp".

EDIT, saw my question was already answered above. Thank you!

Hi, I'm planning an off-grid solar setup and would like to over size my panels to maintain decent production in the winter. For the MPPT at 4kW I would like at least 5kW PV (25% over size). With 2 strings in parallel I'm worried that the short circuit current is too close to the max PV Isc of...

In the end I got the Seplos Mason DIY kit + 16 x EVE 280Ah grade A 6000 cycle cells from qso who offered best price and warranty. I've learned that 10000 cycle cells probably isn't worth much for residential backup application due to inevitable calendar degradation. Thank you so much for your...

Hi guys, Looking into this unit as well for new off-grid system in Italy. Found some recent firmware updates and statements from Victron: Scanning through that thread I also see more support for US users is coming (although it has been taking longer than planned): Scanning through tech...

Interesting. I'm not sure what is the benefit of the battery rack compared to the mason kit? From what I can see: - touchscreen (also present in kit although might differ) - pre-loaded inverter protocols (seems also present in kit) - some edge case heat management. - Better warranty 8yrs...

I see! I didn't actually find the battery boxes/rack systems listed at docan or qso so I'm not sure if there is some deal with the BMS included. Yes so Fogstar from UK (looking at Grade A cells): EVE 304Ah LiFePO4 (currently sold out) ca 3000€/15.565kW (16*154.99£) => 0.1927€/Wh (+ 600€ box...

Thank you so much @houseofancients, I would never have found these options myself. I contacted them as you suggested. @SeaGal That makes sense! Thank you for the info. I'm just getting started to understand these systems. For now I'm just hoping to be able to learn enough to order some good...
