Conext SW4024 - Lithium capability ?

Dave186 · ‎2024-02-08

Seems as if I cant find any consumer support so ended up here. So maybe someone can help. I have a Schneider Conext 4024 inverter/charger on an off-grid system currently connected to a generator and a solar combiner box as power sources. Batteries are Rolls 6V set up in series in a 24v system. I want to move to LifePO4 batteries and am looking at 12v / 300 aH ones that I'd set up in series. I need to know if this inverter can manage these batteries and if there are any special requirements I need to look for when shopping for the batteries. thanks in advance.

The user manul indicates in chapter 4 Lithium / Custom is an option. You need only review the charging requirements for the cells you intend to use. If cells you're interested in can be supported by the Conext SW4024 you're good to go.

NOTE: Regardless of the main charging system in place a BMS needs to be present.

Thanks very much..i re-read the section and spoke about optimized algoritisms for lead/agm/etc. I believe I need to input the specific ones for my new batteries in the "custom" fields". The new lithiums will have built in BMS so should be ok.

I am currently using VERY conservative charge settings for a 30kWh battery bank. This would be a good starting point to and gradually increase bulk voltage if you want to put more into your batteries.

If you have specific questions please ask. There are some minimum unexplained difference between some of the values that you will run into if you start experimenting. Nothing quite like poor documentation!
