    Inverter Low Voltage Cutoff--Why SO low?

    Correct. But when recommended C rate is 0.05C (i.e. 200 x 0.05 = 10A) to have full capacity, you cannot risk to feed the battery like 40A or 50A, even for half an hour. Such an intensive exercise is gonna kill. I charge the battery using a PWM solar charge controller. So with PWM, battery gets...

    Inverter Low Voltage Cutoff--Why SO low?

    Just stumbled upon here looking for a battery discharge protector (low voltage cut-off) for my 200Ah tubular FLA battery which has a recommended DOD of 60%. But I don't want to discharge it more than 30-40%. I was looking at XH-M609 module but it has only 20A relay on it. My 600W inverter may...

    Build a variable current limiter for lead-acid battery charging

    So if I increase solar power, should I keep adding batteries? E.g. to get 50A (@12V) at peak sun hours as I have a plan, I should have at least 500Ah battery to keep the charging rate below C/10. Battery is the most expensive and the fast-wearing component of the solar system (needs replacement...

    Build a variable current limiter for lead-acid battery charging

    I have a 12V, 200Ah deep-cycle lead-acid tubular battery which I charge with solar panels. PV array specs are: Max Power 840W Voltage at Max power 23.70V Current at Max power 35.46A Open-Circuit Voltage 24.22V Short-Circuit Current 41.90A To have a longer...
