    Giandel Inverter remote control

    Oops, I uploaded the wrong pdf. The LED can also be just a diode, but I used an LED to see it pulse. When you push the manual button, it puts power on that side of the switch. Power I don't want the Arduino to see or feel. When whatever is telling the inverter to power down isn't active and...

    Renogy 200 Watt 12 Volt Mono Solar Panel, Compact Design, High Efficiency

    Let me help you both out here. Run an interweb search for electrolytic derate. This will help with Caps on a hot tin roof. Might make a good movie too. Then run a search for electrolytic cap shelf-life. Next, search for electrolytic cap life-span calculator or just cap life-span for more...

    Giandel Inverter remote control

    I have this thing working now. There are several ways to do this but this is the way that I chose. The pdf has a schematic and a physical drawing. There are three wires to solder on the board and three external, including the binary trigger, which is a 1 for on and a 0 for off. It was built...

    Renogy 200 Watt 12 Volt Mono Solar Panel, Compact Design, High Efficiency

    Hold on everyone. I am having trouble finding where I state the panel is bad. That was a question, that's all it was. A question. I implicitly stated just three things. 1. My 200 watt, 12 volt Renogy panel is delivering 60% of rated, in direct sun, (that means no clouds), and other...

    Giandel Inverter remote control

    Actually, my schematic is different than the one above. The switch closes two of the pins on the rj plug. If my old memory serves me, bringing the left pin on the switch to 5v, the unit powers on. Repeating that, powers it off.

    Giandel Inverter remote control

    Nice, where did you get that? I would have loved to have that when I was poking and hoping last night. Looks like I got it figured out though.

    Giandel Inverter remote control

    yes. Inside the remote switch box is an 8-bit micro that does something, but if I bring one of the pins of the rj plug hi, the inverter powers up. If I hit it again, it powers down. I am using an Arduino Nano Every to use the ETXIO4+ to trigger that rj-pin and monitor the power state using an...

    Ok, calm down. Clearly you are passionate in your opinions and believe them above all else. Thank you for your opinions and your efforts to convert me to your positions, but I think I'll pass for now. As a moderator I would think you would be a little less aggressive. Something you might...

    Giandel Inverter remote control

    Thank you sir. I was just sitting here thinking about which micro to use, Arduino Nano Every or a Particle Photon. I really don't want to rip into the inverter, though I have no qualms about tearing that remote apart, again.

    Giandel Inverter remote control

    Has anyone gotten their Giandel Inverter to remotely switch with a logic level, i.e., on/off? The remote control panel that comes with it is a "I'll think about it" button, meaning it uses a microcontroller to take a pulse from the switch and power down. That makes it extremely difficult to...

    Renogy 200 Watt 12 Volt Mono Solar Panel, Compact Design, High Efficiency

    I have to agree with him on the financial points. MPPT controllers are expensive, not all that efficient and fail. I've been in the electronics world since I started thumping tubes as a 12 year old in my pop's tv shop. Electrolytic caps do not last 25 years. No way, no how. Ceramic caps do...

    Renogy 200 Watt 12 Volt Mono Solar Panel, Compact Design, High Efficiency

    Ok, I figured you had a different method than just using a VOM with a higher current test rating than the panel. So, anyone else have input on the Electrodacus?

    Renogy 200 Watt 12 Volt Mono Solar Panel, Compact Design, High Efficiency

    I bought two of these panels and had one out in the direct sun today. Call me greedy, but the max I saw this panel deliver was 120 watts. I am talking Austin, Texas, direct sun at 1400 with the panel tilted to as close to perpendicular as I could get it with a straight stick. Temps were in...

    [PSA] Make sure to properly prepare your connections to aluminium terminal posts in order to ensure low contact resistance.

    Well, someone asked what's best and I answered, gold is best, which is why high end audio and video cables are plated gold.

    4P8S Cell Configuration

    I'm building an 8 cell setup using the Electrodocus SBMS. I looked and looked and looked and the more I looked, the more l liked the Electrodocus. I have my cells configured like this. I don't know if its a 4P4S or whatever, it is what they recommended at Electrodocus so I am good with it.

    Battery Buss Bar Alternative

    Seeing that the buss bars that come with our cells come with a limited number of buss bars, I needed more, as you would building bank. Thinking about smashing pipe or buying copper bar stock, I wondered if this would work. These are 1/0 lugs with 1/0 welding cable connecting them. The spacing...

    EVE LiFePo4 Cell Studs

    So I just opened the packet of hardware that came with my EVE cells and found plated copper bars and Studs. I don't have to make them or buy the, they came with. I am thrilled. They must be listening to Will.

    New Camper Design

    I updated my design with a proper battery config and added a few things. I am fixing to build this out on my truck camper and was hoping y'all could review it for errors and maybe suggest improvements. Thanks very much for any feedback.

    Comments of advice?

    Thanks so much for the input. Very much appreciated. I spent a great deal of time thinking about 12v or 24v and the feedback was 50/50. I chose to stay with 12v because most power I use will be DC and adding a DC-DC converter is just another device to fail. The reason for 3000w inverter is...

    Comments of advice?

    Thanks. All good points. I wasn't aware of the breakers being audio CB's. I will look at a replacement to fuses. I got the 3kw inverter, not because I will use 3kw, but I don't want to run it too hot. I figure I will stay around 2kw for my work, but when I need to plug in my. welder, 3kw...

    Comments of advice?

    Sorry about the drawing size. This site wouldn't allow the original. The Electrodocus is a BMS that uses those small adapter things, (DSSR20), are PWM that control PV input. I have one on each "like" panel strings. The two panels are 100w and two are 200w, hence one per string. The SBMS0...

    I have received nearly everything for my build. I put this together a few weeks ago and been thinking about it. Thought I would post it here and see if anyone has any comments, advice, warnings or constructive criticism of this design. Thanks much!

    Qishou Tech LiFePo4 Cells arrived today

    Just received 8 cells that I ordered from Amy. I found and ordered what should have been Eve cells, but these don't look like Eve cells, do they? All eight look new and all measure 3.29v, so I guess I won't have to balance them. I suppose if they work, I shouldn't worry if they are Eve cells...
