    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. I started...

    Lishen 272AH thread?

    I asked my vendor. Who provided ship tracking. The tracking showed the ships arrival. The vendor projected they would arrive on December 21st. They arrived at port on December 22nd. They are due here in South Dakota today. FedEx sent me notice on Sunday and I have been tracking with FedEx. My...

    Lishen 272ah Cells Aluminum Case Positive?

    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...

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

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

    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...

    Electrodacus with 1.8kWh PV and 2.4kWh battery with water heating diversion

    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.

    Lishen 270ah-272ah cell group buy.

    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...
