Re: [RE-wrenches] Lead acid batteries taking too much current

I thought I would update everyone here about a way to prevent the generator from running too long. It sounds like I am not the only one this has happened to. You can enable Time of Use settings in the System Work Mode menu (at least from the online menus). Enable all days and charge times. It then

Re: [RE-wrenches] Lead acid batteries taking too much current

Our company does not pair any lead acid with a Sol-Ark. Our opinion is that the unit is designed for Li-Ion and that is what should be used. In much the same way that some legacy off-grid products don't play nicely with Li-Ion, we stick with combinations that don't require specialized programming w

Re: [RE-wrenches] Lead acid batteries taking too much current

Sol Ark is adding an end amps (return amps) timer so you can control when the inverter transitions from absorb to float. The problem now is that it is limited to 2% of the programmed or calculated battery capacity for 10 minutes. Once the new firmware is released, it'll be 2% for up to 4 hours. Th

Re: [RE-wrenches] Lead acid batteries taking too much current

Steve, thanks for the call. I am using voltages, rather than SOC to start/stop the generator. I also just reduced the battery resistance to 0 based on your recommendation. Jay, There is a temp sensor. The batteries only got to about 32deg C after 14 hours of charging. I got the 7 hours of absorb t

Re: [RE-wrenches] Lead acid batteries taking too much current

Hi DaveI bet there is no way to install a temp sensor?Question about the 7 hrs absorb time. Where did you come up with that figure. Is the 5% adjustable or the adjustment is in the battery capacity?ThxJayOn Oct 4, 2024, at 8:30 AM, Dave Tedeyan via RE-wrenches wrote:Hi All, I have inherited and d

Re: [RE-wrenches] Lead acid batteries taking too much current

Dave, I need to give you a call... I need to make a new video with some changes. As for the generator starting but not stopping it's a mix between the battery resistance and the SOC percentages... are you using voltages to start/stop or SOC% I'll give you a call in a few mins to discuss further.

[RE-wrenches] Lead acid batteries taking too much current

Hi All, I have inherited and done some work on an off-grid system with a Sol-Ark 8k inverter and now has a new set of 16 Rolls S6 L16-HC batteries (only about a month old). There is only 3.9kw of solar, and there is a 12kw generator. First of all, thanks to Steve for putting out that webinar a li
