    A19 Edison screw base

    I forgot to mention, splitting the h2o is achieved at a much lower amperage if you add some nitrogen. Check Robert Murray-Smith for making hydrogen and the bromine battery.

    A19 Edison screw base

    Hello Josi, Yep unusual is more interesting. I am not at the level of confidence to compress yet. Although I have a source for low compression vessels I may fill with carbonized hemp. I understand they will hold 10% hydrogen by weight at 1 atmosphere per pound of hemp. If it works I will see if...

    Why is this a bad idea?

    Hello rmaddy. I have not figured out the cut and paste thing here. Please bear with me. On 12V that is only 480W supported. The rest of your panel wattage can't be used. If you had a 24V setup then your charge controller can support 960W of solar. Sort of my understanding. The reality to my...

    Why is this a bad idea?

    Thank you for all the information. The panels are rated at 24vdc but open they measure 39-40 vdc. I thought 24 volt batteries setup would be the most efficient use of power. I was concerned wired 12vdv was clipping and wasting power. It is back to 12vdc, cleaned panels, fixed something...now I...

    Why is this a bad idea?

    270w panels Rated Power: 270W Open circuit voltage (VOC): 44.4 V Max power voltage (VMP): 35.5 V Short circuit current (ISC): 8.25 A Max power current: 7.60 A Power Tolerance 0/+3% Maximum system voltage: 600V (UL) Fuse Rating: 15 A IP65 Junction Box w/MC4 Compatible Connectors Frame: Anodized...

    Why is this a bad idea?

    I was looking for maximum efficiency. The 12 volt system charged the batteries in short order. The 24v system has yet to charge the batteries. I did discover the panels were covered in pollen and cleaned them. Still the 12v out preformed 24vas far as battery charge capacity.

    Why is this a bad idea?

    I did not see a wire direct option in the manual. The panels are 24vdc so that would not work with a 12vdc inverter. I had the battery bank wired as a 12 volt bank. It charged quickly and I assumed the excess Solar was being clipped. Now as a 24 volt battery system it does not reach full charge...

    Why is this a bad idea?

    I have 4-6volt deep cycle gold cart batteries(GC2-6v 105 min @ 75 amps) wired in series for 24vdc to match the input of my 3-270w 24v panels. I have a GIANDEL 4kw 12v inverter. I see that picking up the postive and negative of each 2 pack of batteries is 12vdc. If I run leads from both 2 packs...

    Epever controller

    I have the cables that came with the inverters. Neither over 18" in length. I will post screen shots when I return. I guage the battery level based on the number of bars indicating battery charge. They remain at 2 bars out of 8 most of the time. At full sunlight they charge (8 bars) in a little...

    Epever controller

    I have both the 2kw is wired in the 4kw is not. I am concerned it will overload the system as it stands.

    Epever controller

    The battery voltage, as I remember is in the 13.5 to 15v range. Here is what I think I know from what the meter says 12 volts x 3 amps is only 36 watts. A fraction of 1 panels output. I am wasting the capacity of the other 2 completely. I do have a 4k/8k inverter at 12 volts. I expect even if I...

    Epever controller

    I mispoke the panels are rated at 7.6a, I confused it with fuse rating. 3 wired in parallel should increase the amperage while the voltage remains the same. With that consideration 3 panels in full sun should produce more than 3 amps total, I think. The EP controller never shows above 3 amps. My...

    Epever controller

    Hello I have a 4215BN, 4 - 6v gcart batteries and 3 - 270w 39v 15a solar panels 3p. A 2000w inverter with two 120v. 1 showing 100v the other 110v The Charge controller shows 40v but never above 3amps, full dun shade, clouds... 3 panels in parallel should be close to 30amps. The panels are...

    A19 Edison screw base

    A.Justice blanket away. Your explanation clearly demonstrates your intent. Ok now that you ran the numbers I have to try just to know... maybe it will run a single A19 in the deep dark bowels, the kitchen. I have not posted pics before but I will give it a shot. The house was vacant for years...
