    So Im going to connect the solar panel to the SC ports, and the battery, I'm going to connect to the center ports but I'm going to connect the hot lead through a normally closed relay where the relay is actuated when the ignition key is in the on position. This should guarantee that the system is not connected when the alternator is running. And that last set of ports I'm going to just remove those wires since I wont be using them for any lighting of any kind... does that resonate with how you have yours hooked up in terms of properly identifying the ports?
    Correct, the left most ports are for the solar panel, the center ports for the battery, and the right most ports for the load (not used if you're using it to charge an automotive battery, in my case that is where the cable going to my "control panel" for the lights is hooked up).

        A device like this with a motorcycle battery would be really useful on a camping trip for tent lighting etc.

        What's the USB port for? Charging a USB device?

            That is essentially what I have setup in my shed, the battery is a CB12a-a motorcycle battery I've had sitting around for years (I ordered a CB12al-a motorcycle battery from Amazon a few years ago and they sent the wrong one [same size but terminals reversed] and since it was hazmat they didn't want it back after sending the replacement, since most motorcycle batteries ship with the acid separate it was still good so I figured I'd use it for something), though a dep-cycle or LiFePO4 battery would probably be better suited to the task.

            After going through my switch panel (just a project box with 3 automotive switches and the volt meter on the front) it powers a 12v LED motion sensor light on the front of the shed, and an automotive LED flood light attached to the ceiling for interior lighting.

            correct.

                Well, I got the panel hooked up to the car kind of willie-nilly for the time being but the back of the car gets tons of direct sunlight for most of the day. I was really surprised when I put my ammeter on it and saw it was charging the battery at .94 amps ... almost a full amp! That's quite amazing for a solar panel of that size.

                Thanks for the tip on that purchase, It's going to work out well.

                    Bosch 12V and 18V chargers modification
                    by Petr0x
                    Hi, I would like to share with you small modification to your Bosch tool 12V and 18V chargers.

                    You can use it for almost all Bosch chargers what I have seen, for example part numbers GAL 18V-20, GAL 18V-40, GAL 1880, GAL 18V-160, AL 1820, AL1115CV, AL1130CV.

                    Bosch (today also other brands using the same system like Wurth, Fein) does not care if you destroy your batteries, because they can sell you new ones. So the marketing is telling you only about speed of the charging, so you will not wait for your batteries to charge too long. Me as a customer want the tools and batteries...

                    Help please with identification of few components for troubleshooting (Solar Water Fountain circuit)
                    by Techie_hobby1
                    Need some help please with a few components on this small board so that I can troubleshoot the circuit.

                    The PCB is a Single sided board fairly simple circuitry has a +ve and -ve Solar cell power input, a 7.4v 1500mAh (dual 18630 cell) power in which the Solar panel charges the cells, and lastly the Output goes to a DC connector...
                    J1 is actually 1P1T Switch (in ON position completes Battery cell circuit
                    J2 - to DC Output
                    J3 is Battery cell connector

                    however I am struggling to identify if:
                    Y1 (SOT-23) are NPN Transistors, MOSFET's or 11v Zener's....

                    MPPT 60AMP Solar Charge Controller 12V 24V 36V 48V DC Battery Regulator Testing results on 12 volts
                    by sam_sam_sam
                    I bought one recently but this is the first weekend that I did not have work Saturday morning or the sun did not want to cooperate with me but today it is coordinating with me and I run a very simple test on a 12 volt battery pack and it stop charging ar 14.4 volts

                    Here is the website link where I bought it from

                    https://www.ebay.com/itm/395434828814

                    I ran this test with a new 12 volt solar panel that has a no load voltage of 19.0 and an output current of 9.1 amps

                    I do not remember the starting voltage but the charging amps was 1.4 amps
                    ...

                    Solar Inverter - SMH-II - 2 missing capacitors
                    by Cama
                    Hello,
                    I need help to find the value of 2 missing capacitors ( C102 and C117) on my Easun SMH-II mainboard (solar hybrid inverter). I circled it in red on the close-up picture. The 2 old capacitors are completely missing, so I have no reference. Does anyone have this board and can tell me the value or make an educated guess based on the location ?


                    My model is : EASUN SMH-II 7 KW
                    Mother Board : P/N 18947-002401250250
                    Maybe the EASUN SMH-II 4.2 KW have the same capacitors


                    Thank you...

                    Sell or Shim Solar panels?
                    by eccerr0r
                    Well, due to my grid tie inverter not accepting high voltages, and the fact that the lions in my solar panels are 36V (72-cell) I think I need to stick with 72-cell.

                    However I have a few smaller panels that are 36, 32, and two 30-cell. The 36 and 32 together run at 75% efficiency (and subtract more with additional inefficiencies) when running in parallel with the 72-cell panels. The kicker is that the two 30s... generate 0% power when connected in parallel(!)

                    So now what to do with these small panels?

                    I could sell them...

                    Or I could shim them....
