More Modules and more delays

(thanks goes out to the supplier for a great transaction!) I started testing…

Circuit Breaker and Shunt Trip

Thanks to Rohan Wilschefski’s advice I found a second hand Merlin Gerin NS160 N circuit breaker from eBay. I then found a compatible 48V 30w shunt trip. This will allow the Batrium BMS to disconnect the Battery from the inverter in case of emergency such as Low Cell Voltage, High Cell Voltage etc. Merlin Gerin…
