    Stacked Panels with a slide out feature when parked.

    FYI.... 15 series 80/20 (1.5" square), is slightly thicker than the average solar panel frame side wall. I'm building a perimeter frame from it to surround my 4 100W panels. It will mount like a roof rack.

    Renogy DC DC Charger w/ MPPT

    Can you set the "Boost" to 13.9-14.0V. Under your conditions, that might be better.

    MC4 vs PowerPole Crimpers?

    I just crimped some spade terminals on some 16AGW wire. They were the style that has two open "U"s on each. I used the 14AWG position on my MC4 crimpers. I had to crimp each one in two places. They made perfect crimps on them.They rolled the sides over the top. At the other end of the wire I...

    MC4 vs PowerPole Crimpers?

    I have done 30A & 45A A/PP, 10AWG, 12AWG, and smaller wire. I crimped every one with my fancy German MC4 crimpers. They all fit i n the housings and hold strongly. If it is a different profile, then it is damn close. The only thing missing is the little block that holds the nose of the PPs. So...

    MC4 vs PowerPole Crimpers?

    Tbe crimper for SB50/PP75A and larger puts one big divot in the tube. I'm going to try my hexagonal hydraulic crimper to crimp my PP120A to 4AWG cables. I can't picture a reason it won't work, but i can't say for sure until I do it.

    MC4 vs PowerPole Crimpers?

    And you would be wrong. My German made Staubli PV-CZM-32.6020 MC4 crimper crimps 15-30-45A power poles just fine. It takes a little more care to line them up. The shape of the crimping part of the die is the same as A-PP.

    Has anyone used the Kisae DMT1250 Abso 50A DC-DC Battery Charger with MPPT?

    They say the memory is the 2nd thing to go. Now what was the 1st thing? I suffer from CRS at times, too.

    Has anyone used the Kisae DMT1250 Abso 50A DC-DC Battery Charger with MPPT?

    What were you doing that you accidentally hit the switch? That thing is buried and hard to get to with my big fat fingers. The eraser end of a pencil helps reach it for me.

    Has anyone used the Kisae DMT1250 Abso 50A DC-DC Battery Charger with MPPT?

    I'm not sure, but if it is like the voltage limiter, it turns the unit off if it goes over the limit. I don't have a circuit breaker, just fused. On the solar input I have a 11" 10 AGW pigtail, fused on both +/- and terminated with a 45A Anderson Power Pole. On the House and Starting...

    Has anyone used the Kisae DMT1250 Abso 50A DC-DC Battery Charger with MPPT?

    FYI. If you download the PDF of the manual and print it on 8.5" x 11", it is easier to read and you can put it in a binder with all the other manuals for your stuff. I wish Kisae would make a PDF of the Flow chart for setting the parameters on one page. I'd take and have it printed on 11" x 17"...

    Has anyone used the Kisae DMT1250 Abso 50A DC-DC Battery Charger with MPPT?

    Go read post #33 and the voltage amperage limits. The only problem is if the panels produce more than their VOC rating. Down load the owners manual for the DMT-1250. It lists different figures from the spec sheet. Specs, as they should be...

    System can't keep up after upgrades and reconfiguration

    If he stays somewhere with shore power or has a generator, most RVs have a built in 12V charger.

    System can't keep up after upgrades and reconfiguration

    Exactly. MC-4 connectors are not designed to be taken apart regularly. Anderson plugs are designed to be self cleaning as they're connected/disconnected. Some of the Solar Generator manufactures have decided they make the best choice for their portable panels, too.

    System can't keep up after upgrades and reconfiguration

    Don't combine them on the roof. For the two portable panels 10-12AWG leads and hook them into the circuit at or near the SCC. If you need to, put a small bus bar or terminal for all the solar and then run one set of wires to your SCC. Use the largest AWG your SCC will accept for that last...

    System can't keep up after upgrades and reconfiguration

    Can you mount the panels in a way that they can be tilted towards the sun? How much extra room do you have? Maybe some extra panels you can hang on the side when you're parked. If I find the 400W I have now is not enough, I've thought about getting a couple more and either hang them on the side...
