    Does anyone know the "Cycle capacity" parameter value for the EVE 280AH battery in the XiaoXiang BMS app? Thanks.

    Please disregard my question. Found the info in "Overkill Solar BMS manual" " 3.2.2 Cycle Capacity This parameter is used to calculate state of charge. In the real world, batteries do not meet the designed capacity printed on the cells. It can be higher, if the cell was underrated, or it can...

    Top Balance voltage drops

    I top balanced the 4 EVE 280ah cells to 3.61vs and let it parallel for 3 days. Day 1 at 3.61, Day 2 at 3.571, Day 3 at 3.541v. Will it continue to drop to 3.5v or 3.4v? I plan to put the BMS on and let it be. All cells measured exactly the same or maybe off by 0.001v or so. I guess LiFePo4...

    Two x 24v battery banks and one charge controller....

    Hi, I have a question about one charge controller to charge two 24v battery banks with BMS. Do I hook both battery banks to the command bus bars (positive and negative) and then the one charge controller to it? What if the one bank finished early and the other bank still taking charge? or...

    Battery monitor lug size?

    Hi, I am trying to locate the spec of this popular battery monitor shunt terminal lug size. I haven't purchase it yet because I am in the planning stage. I searched the web, web videos, manuals, read comments, none state which size lug to use. If someone has it and could share the terminal...

    Parallel 1/0 awg or 0 awg to max the amperage

    I want to see if I could combine (2) 1/0 awg wires in parallel and not using 4/0 wires. The reason is I have plenty of 1/0 awg copper wires and want to avoid buying 4/0 awg wires. I plan to use it in the 24v system with the EVE 280 batteries. I see the 1/0 awg could handle it if you look at...

    EVE 280 - top balanced - want to use without BMS

    New here with EVE 280. I am in a rush to put 4 EVE 280 Cells in service without BMS. It seems like everywhere is out of stock for 4S BMS due to a rush of 275a/280a orders by everyone here. I will top balance the 4 cells to 3.65v in parallel and then series them. Plan to hook it up to a 12V @...

    Is it ok to run AC and DC wirings together inside the conduit?

    Is it code compliance to run both AC @ 240V and DC @ 200V in the same conduit? I had wires ran long ago that planned for AC generators along with live 240VAC wires for air conditioners, but never used the spare wires. Only the air conditioner wires are live. I plan to use the spare wires in...

    Any all in one PTZ camera that has temperature sensor, water leak, humidity alerts?

    What about an All-in-one for the remote monitor for the solar shed and equipment out in the elements? I am looking for an All-In-One PTZ camera that could be remotely controlled and has the temperature sensor, water leak and humidity alert notifications via email or phone calls. I know you can...

    What LifePo4 BMS for 14S battery at 46.2v nominal ?

    Hi, New here. I need help with a BMS recommendation for an odd 14S lifepo4 battery with at least 100a for a 48v system. I know 16S is ideal, but my inverter could take the low 36v and 64vdc. It is not in the sweet spot of 16S, but I believed the 14S would do for the range of 46.2v to 38vdc...

    Solar panel voltage drop calculation using VoC or vPmax?

    I plan to series two together with 330W panels, the specs are: Isc 6.07a VoC 69.7v Ipmax 5.70a vpMax 58.0v The total series voltage is 139.4vdc with VoC. I plan to run this around 100 ft distance with 8 awg wires. I have done the voltage drop calculations, the drop is below...

    Goal Zero 1250 worth it?

    It is worth to buy the old-new stock Goal Zero 1250 for $600 still using SLA battery? Heavy too. It could also connect an external battery to it to extend the usage. Or when the internal is dead, one could get the Lifepo4 type battery as a drop in? or the cost is around the same as the...

    Magnum MS4448PAE Inverter and battery matching.

    Hi, I have a question about Nominal Voltage and Fully Charged Voltage on the Battery Hookup's newly posted BMW 57.6v 2KW module and how it might work with the MS4448PAE inverter that I have and can takes VDC voltage from 36 to 64v. I know the inverter could take the 57.6 Nominal voltage, but...

    Split phase 240V relay SSR(Solid State Relay) control via 110V?

    Could someone recommend a 240V split phase SSR relay that could be controlled by 110V power? I want to use the relay to shut off a 240V split phase load. I have some idle loads that consume power and would like to flip it on and off completely as needed. It needs to be a 240V/20amp SSR...
