    Battery SoC% Discharge Question

    Both voltage graphs were helpful. Do you have a battery amp chart?

    Not connected to grid, solar through house circuit possible?

    That is for exporting inverters. If he uses an off grid inverter, it is normal load to the grid.

    What do you think is going on with this bank?

    Once you know the cutoff, drop charge amps to 10 amps. By charging right under the bmd cutoff, the high cell will stay under 3.65v

    Signature Solar Supply Store...a prototype??

    It would be helpful if they had a directory of electricians and installers willing to do limited work. Like Home Depot pro directory.

    True lies for lead acid battery ...

    Unclear from a quick scan if they tested FLA, or just AGM. Pulse chargers were developed for FLA. The free movement of the sulfur ions in FLA may make a difference.

    Battery SoC% Discharge Question

    If I calculate it right, you are getting about 250 ah, or about 13kWh. Discharging to 25%, that implies 17kWh capacity. Voltage chart to see if you are fully charging.

    Signature Solar Supply Store...a prototype??

    How about one per federal reserve bank district, or federal circuit court? Also Radio Shack. They could have rebranded as Solar Shack if they survived a few more years. Harder to diy grid connected systems, and deal with all the new safety requirements for a permit.

    True lies for lead acid battery ...

    How about a desulfating charger that pulses voltage to slow down aging?

    Growatt: How to charge batteries on PV to a set amount ?

    What difference does it make when you charge from pv? Maybe more batteries so you don't have to charge overnight.

    Battery SoC% Discharge Question

    What are your charge settings? Maybe the BMS is cutting out early due to cell overcharge. How does the power out look? Getting close to the 400 ah?

    PV not staying constant

    I have no idea what you mean by "3kw" for a hot water heater. My guess us the system works as follows: PTC is on hot water side of the tube. When the tube heats up, it starts the pump. If temp is too low, it shuts down the pump. There may be a 2nd thermostat at the hot water heater. If when up...

    Need feedback on component selection for a small but expandable off-grid system

    I belive the reason victron is not more popular is that they are not UL Listed. They have CE for Europe, but not UL for USA. For the cost of two victrons, you can get the 6000xp, which includes the charge controllers. If you need more power, you can parallel a second. It would be easy to stay...

    Not connected to grid, solar through house circuit possible?

    You might not need an interconnection agreement if the inverter cannot export to the grid, such as the 6000xp.

    Prices dropping, will this continue?

    Solar and battery tax credit is currently through 2033. I say buy batteries now, and replace in 2033 if the credit is not extended.
