Hello Wrenches, hope I'm not stirring up a hornets nest here, with all the talk about EG4 and some of the "All in One" inverters, I thought I would just mention that after careful review of EG4 and SRNE's manuals, I wouldn't use thier inverters on any Surrette/Rolls Batteries out there, if I were involved in the installation, since you cannot control absorb timers, or control when the inverter/charger transitions from absorb to float, I would be very hesitant to use these inverters with any lead battery. Lithium looks to be good, but IMO lead would be a no-go...
They are not configurable enough to charge most lead-acid batteries correctly. I have reached out to both Signature Solar and EG4 regarding this matter, and to date, the messages sent over the past four months have not been responded to. I sent them another request today; hopefully, at some point, I will be able to make contact and work with them to get a solution. The Midnite AIO is programmable, but I have concerns about how it shuts off automatically when the generator is running, specifically when the State of Charge (SOC) reaches 80%. I have been speaking with Midnite about allowing the inverter to charge to 100% for this, but I think they are waiting for more field feedback before making a change. I have suggested that they set a timer that will go to 80% normally, but 1-2 times a week it'll take the lead battery to 100%... As you know, this isn't a problem with LFP or Li-ion... only going to 80% on lead all the time is going to result in severe capacity losses. With Sol Ark, you should contact them and obtain a firmware upgrade that they have developed for the lead batteries. This will enable you to control the end amp's time. You should also disable their battery resistance settings, as these can raise voltage and current when the battery's internal resistance is too high. This could cause damage to your sealed batteries, as temperature compensation is not considered. <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> <http://www.rollsbattery.com> Steve Higgins ⋅ Technical Services Manager t +1.902.597.4020 m +1.206.790.5840 f +1.902.597.8447 e [email protected] <http://www.facebook.com/RollsBattery> <https://www.youtube.com/user/RollsBattery> <https://www.youtube.com/RollsBatteryEngineering> <https://www.youtube.com/RollsBatteryEngineering> <https://www.youtube.com/RollsBatteryEngineering> <https://www.linkedin.com/company/rolls-battery-engineering> <https://www.linkedin.com/company/rolls-battery-engineering> <https://www.linkedin.com/company/rolls-battery-engineering> <http://www.instagram.com/RollsBattery> <http://www.instagram.com/RollsBattery> ------------------------------ CONFIDENTIALITY: The information transmitted herein is intended only for the addressee and may contain confidential, proprietary and/or privileged material.
