    Battery DC Isolation between inverter and battery

    Greetings, I have a 5kwh solis hybrid inverter (S5-EH1P5K-L) with 12 (390W) JA solar panels . I was wondering if there's any requirement to install any DC isolation between the battery and the inverter or they can they just be simply connected to each other?

    Battery Can a battery exchanger solve our EV problems?

    I personally think the EV concept needs a new approach. Instead of spending hours recharging the EV the user just swaps the discharged battery with a charged one. The exchange time would be les than it took to fill a standard car with gasoline. You drive into a narrow lane just like you now...

    Battery Car battery question

    I have just bought a new battery for my car. It's a Varta battery. Before fitting to the car I tested it with my Topdon BT50 tester and was surprised to find that the health was only 69% 689A. Charge was 100% 12.65V. Should a new battery have a health of 100% ?
