    Sixtysix 280ah Cells from Deligreen

    gloves are difficult at times. I use the mechanics gloves, I need to insulate my tools better. I really appreciate your posts. some people think they know too much when in reality they have no hands-on experience with these types of powerful batteries. thanks for your efforts. I kind of wish I...

    DIY 24-volt 560Ah LiFePO4 battery (272x2=544Ah) with Electrodacus SBMS0 and Electrodacus DSSR20

    cells arrived Sunday January 17th, 2021 via FedEx at 920am. slowed by the midwest blizzard by 3 days. yesterday I labeled all cells on the new 32 Lishen 272Ah cells with red tape on the positive end and a Dymo label that says positive. Lishen 272Ah cells have no labels but the black plastic...

    Sixtysix 280ah Cells from Deligreen

    I ordered hydraulic crimpable cable ends that will crimp to make some battery interconnects for my new 32 cells I received via FedEx on Sunday the 17th of January. all cells are Lishen 272Ah. the busbars supplied by the vendor will only parallel 16 of the 32 at a time. so have to go to plan b...

    mine were supposed to arrive Thursday; but due to midwest blizzard conditions, they finally all arrived on Sunday January 17th, 2021 morning at 920am. but they are all here. i unpacked them and started paralleling them together for top-balancing. all cells in perfect condition. no problems...

    Lishen 272 set up - What am I forgetting?

    the Lishen cells have 6mm studs. mine came with 16mm long ones on the 1st set of 32. they did not come with enough bus bars to parallel them together. I made one 16 cell 2P8S 24-volt battery bank and I am charging the other 16 cells ever so slowly with the solar power from that bank with a Riden...

    BiduleOhm's project design WIP (30 kWh battery, 10 kW inverter, 16 kW PV)

    I tried the calculator and you have to put in dc then it doubled the 30 feet or 60 feet and 60 and 120 feet respectively for 10 gauge PV wire and came up with 3 or 5 percent voltage drops respectively for the30 or 60 feet runs. thanks for that link. from lowes home improvement store.

    my second supplier of Lishen 272Ah cells also noted to me to put insulating sheets between the cells and under the. I have not done this yet, but have no real information on the leakage topic/potential problem. hope to read more actual detailed information if it is a real problem or not? :cool:

    voltage drop on dc 10 gauge wire?

    DC / single phase calculation The voltage drop V in volts (V) is equal to the wire current I in amps (A) times 2 times one way wire length L in feet (ft) times the wire resistance per 1000 feet R in ohms (Ω/kft) divided by 1000: Vdrop (V) = Iwire (A) × Rwire(Ω) = Iwire (A) × (2 × L(ft) ×...

    voltage drop on dc 10 gauge wire?

    I still don't understand the voltage drop calculations. the 2 panels in parallel come into the DSSR20 at around 36 to 39 volts. this is on a 60 feet run. each dssr20 cost about 37 Canadian dollars 91 Canadian dollar is currently .79 Us dollars so the DSSR20 is 37X.79=$29.23 to control 500 watts...

    DIY 24-volt 560Ah LiFePO4 battery (272x2=544Ah) with Electrodacus SBMS0 and Electrodacus DSSR20

    yesterday January 13th, 2021: I hooked up 2 more 250-watt 60 cell PV panels on the south-facing array. the 6 panels (1.5Kw array) were producing 1162.7 watts and more at times and charging the 2P8S 24-volt LiFePO4 battery bank with 41.898 amps. see pic below. I think the only load at the time...

    BiduleOhm's project design WIP (30 kWh battery, 10 kW inverter, 16 kW PV)

    no, your calculations are way off or at least misunderstood. 2 panels are in parallel at the array. the long runs (south-facing array)about 60 feet require 1 red PV 10 gauge and I black PV 10 gauge wire. so 120 feet that is for 2 panels. the short runs (west-facing array) are more like 30 feet...

    BiduleOhm's project design WIP (30 kWh battery, 10 kW inverter, 16 kW PV)

    i have only 3 feet of 4/0 wire from the batter to the inverter positive busbar. so no real expense there. 10 gauge wire is 250 dollars per 1000 feet. shipped to me still cheap. I like your logic I plan on using resisitive wire and hydronic heated floors strictly off the excess solar pv...

    the panel with 1/3 shorted would be located in your living quarters where you want the heat. the 2 other panels would be outside. this requires no other components. I am not sure where everyone(some people report incorrectly) keeps saying it takes larger gauge wire they are obviously wrong and...

    I totally understand the aesthetics issues. I am out in the country without any real close neighbors on a long private driveway, so free to play with panel location a bit more. did you look at the Electrodacus dssr20 with diversion as a heating option? the excess electricity from the solar...

    I built an outdoor fully insulated solar power shed for the batteries and charge controllers and inverters etc 8x8 feet x 8 feet. wish it was bigger. keeps the little one safe from it all. and keeps nosy people out. I use a heat lamp bulb but need to control it as it actually gets up to 80...

    Lishen 272AH thread?

    this order of 32 Lishen cells is arriving Thursday January 14th, 2021, by end of the day via FedEx. so 57 days total delivery but they arrived at the port in long beach California on December 22nd so the boat unloading backlog and custom clearing is the slower part.

    update for you: FedEx says my order of Lishen 32 cells will be delivered by end of the day on 1/14/2021. so once FedEx gives notice of their possession, it is 5 days later for me to receive them. I ordered on November 18th -- with now January 14th delivery date thru 3 federal holidays -- this...

    it could be that one DSSR20 can work with all your panels (6 100 watt panels). Dacian is an expert engineer. I run 2 250 watt panels on each DSSR20. which is exactly why it is good to consult with Dacian the engineer and vendor of the Electrodacus SBMS0 and Electrodacus DSSR20's he is really...

    I have not received them yet. But I know that FedEx has them in their possession and they are no longer on the ship. I expect to get mine in about 3 to 5 days. That was the time frame on the 1st 32 cells I already received. FedEx is more dependable than ups. But we have no control who the vendor...

    one other thing to consider. I chose to do a ground mount as I did not want to climb up 20 plus feet to the lower edge of the roof on my 1840 to 1880 vintage house with a ladder in the winter or summer for that matter. I do enough ladder work without asking for more. climb a ladder in the wind...

    Generator noise is rather obnoxious, but you may have it (or want it) for an emergency just in case( i wore out 3 or 4 generators in off-grid use in the mountains of Bolivia where no electricity was available. I would suggest more solar panels and buy a bigger battery bank. I bought 64 272Ah...

    how many cells do your 100-watt panels have? ok, 64 cells. you can parallel them and run 2 into every DSSR20. the DSSR20 is capable of 24 amps but is rated for 20 amp input each. parallel 2 panels outside on the roof 1st. the SBMS0 is the BMS and it will be located inside in a dry location. the...

    It sounds like the amount of mounting space is your primary problem. Dacian the owner of Electrodacus indicates you can use 30 or 36 cell panels in groups of 2. with the dssr20. the amperage of the DSSR20 can handle up to 24Amps but is rated for 20 amps each. a 24volt battery bank likes to...
