    Inverter DC input minimum voltage too hight for battery pack

    Hi guys. I have a very interesting second-hand solar panel kit for cheap. I have some questions. I want to store the energy in my battery pack 12v but i can make it to 24v. The big problem is that the inverter has a minimum DC input of 100v (220v nominal). The kit is huge : 24 panels of 235W...

    Cells in series and parallel at the same time for balancing and use ?

    Hi, I have a LiFePO4 4S 12V "100Ah". One cell has much less capacity than the others. It has 70Ah while the others 90Ah. I'm fine with it but i was wondering if i could do something. I know that the best solution would be to buy another cell with more capacity. My issue is that the weak cell...

    Charging NiMH cells with a bench power supply ?

    Hi, 1.a) Can we also charge a NiMH cells with a bench power supply as a lithium cells ? I put 2 AA and 2 AAA NiMH (2500 + 2300 + 800 + 800mAh) on charging in parallel. They all were empty. I'm charging them on constant current at 0,350mA (so 1/10 capacity) and i set a maximum voltage to 1.55v...

    How to determine the current from AC to DC ?

    Hi guys, I have a basic question. When a switch is rated for 30A 250 VAC max, how do you calculate how many amps can it handle for 12V DC ? If i go for 250*30 = 7500W There is no way that the switch can handle 7500/12=625A. So how do you convert from AC to DC about the electric current ? Thnx

    Daly BMS going on sleep mode - how to wake up ?

    Hi, My battery is connected to a 3 pole led switch. From that, i want to power accessories, for e.g. a light. But the BMS is going on sleep mode after some time of inactivity, so i have 0 voltage (0.04v exactly) on the P- and Pos terminal. How do you wake up the BMS for a battery power usage ...

    Are my BMS settings good for more lifetime ?

    Hi guys, I bought an 100Ah LiFePo4 4x3.2v cells. My system is 12v. I have a Daly BMS. According to these charts (https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/), i want to use 20%-80% range of the total capacity for more lifetime. Are my settings correct ? Thanks.
