Yes, now that I have learned a bit more I should have spent a bit more $$$ and done a 150v/30a or even larger to have more panel options. The Victron MPPT 100v/20a is my "starting to learn" kit and I have already learned a lot. I will still use it forever to charge the golf cart once I get...

I may do that. I don't need to have it running 7x24x365 it's going to be used on 12V on the RV when we use it on property but don't start the generator, and would be used Fall, Spring, Summer (east Tennessee) to charge our LANDMASTER EV UTV (48V) Eventually we will have whole house solar...

and the Battery Manufacture did state to charge at 58V for the 48V battery

What brand and model/watt panel did you get. did you do 2S 2P or just one 400W panel?

I just bought the same Victron SmartSolar Charge Controller MPPT 100/20 I am curious about the specifications on your Solar Panels. =Rated Maximum Power =Current at Pmax (Imp) =Voltage at Pmax (Vmp) =Short-Circuit Current (Iac) =Open-Circuit Voltage (Voc) =Maximum System Voltage =Maximum...

Hello Victron Smartsolar Charge Controller owners. I would love to see your panel and battery configuration if you have the MPPT 100/20 I am trying my best to come up with a panel configuration that would work with the MPPT 100 20 that is overkill for 12V battery but able to do 48V (charge at...

I bought a Victron MPPT SMART SOLAR MPPT 100/20 In using their online calculator and using their WEB tool, I could not come up with any panels that my local panel seller on FB Marketplace had that would work for 48V Batteries. Worked with 12v and 24v fine. So I pulled down their EXCEL...

I'm doing 2s2P and is working well for the 12V RV thus far (two days in) The VICTRON tool online allows me to manually put the SCHUCO Panel specs in and it says 2P2S is fine. I will just have two spare panels for now. (own 6 total) They were only $35 each so not a huge deal, and it's a...

It seems like the WEB Calculator doesn't like 48V for batteries. When I try to use a panel that CurrentConnected said should work, although not confident the name the Victron Tool has for the Rich Solar 200W as it doesn't show SPECs once you select the panel and the names are not always 100%...

Thanks!! I went on Victron's WEB tool and it has this panel and comes up perfectly for 24V. Thanks for sharing. I tried Victron's too to change battery to 12V and 48V and no configuration of these panels with work, only for 24V. The Victron 100 20 is just too limited. Thanks again for...

I used Victron's Spreadsheet (There web version had ZERO luck doing a 48v Panel solution) and found I could do either 12v or 48v with Rich Solar 200W RSM200 from Current Connected in a [3 in Series] [2 Parallel] configuration It does report the over 30% over sized for 12V but that's ok...

Yes, I am rapidly coming to the conclusion I should have bought Victron 150v/20A instead. The panels are SCHUCO MPE 220 PS 09 220W VMPP 220W IMPP 7.38A Voc 36.8V Isc 8.12 A The Victron Spreadsheet app says I can do 2s2p and have a "workable" 48v configuration...

When I do this same calculation on the Victron WEBSITE, with "Custom Module" setting so I can manually input Voc, Isc, Vmpp, Impp, there is no MPPT 100/20 configuration that works.

Yes, it's the problem.... I primarily need it for the 12V RV battery, so I guess, money not totally wasted... I just would have liked to be able to move it back and forth from RV to Golf Cart. At this point it looks like I will be researching my MPPT options with 150V or more head room maybe...

Thanks for the insights Sunshine_Eggo and JoeHam. I see the temperature issue for the 48V. If I use Victron's spreadsheet I can play with Max and Min Temperature If I bring the Max Temperature down to 97F, then the Min PV voltage goes up to 58.0V. The restrictions of this Victron MPPT...

are you charging 12v, 24v, 36v, or 48v?

And that's charging a 48v system right?

Can you tell me the brand and model of your 2 in series 72 Cell arrays? I am struggling to get the tools to give me options even for decent 12V performance, and the webtool won't give back anything for 48V battery using MPPT 100/20
