Iam in process of buying an EMUS BMS system for my upcoming lifepoe upgrade and would like to obtain some knowledge from EMUS users.
How is the charging from the MPPT’s controlled, is this done via canbus with DVCC enabled ?
I also got a wakespeed WS500 regulator but it has not yet been installed, will this work the same way as above ?
In addition to above, I understand that I need a contactor or solidstate relay as an mean of ATC ?, but guess this is more like a second barrier to prevent overcharging ?
Primarily, the Cerbo will read the max permitted voltage and current for charging / discharging from the BMS via CAN data, so it is important that the BMS uses a standard format.
The Wakespeed regulator may not be controlled by this - I don’t know if they communicate with the Cerbo too.
The contactor is a last ditch isolation device if the software control of charging / discharging fails. It is also worth noting that you may want to add some emergency lighting on the battery side of this isolator - a few low power led bulbs should not adversely affect the battery in the short term.
Thanks Mike, the Wakespeed should work with the Cerbo but looking for people who have real life experience with this setup as I need to know if the cerbo actually controls the wakespeed or just sharing information. Not sure I understand what you mean with the leds but I will have a separate AGM bank in case something goes wrong with the lifepoe setup
