If I only installed Newmar or SL sanctioned devices, my coach wouldn't satisfy me. Some are made by others and bought on Amazon while other are DIY projects that are custom to my needs. I installed all sorts of smart devices in my S&B home (as well as my coach). (As well as to being able to control the duration of the charge bridge activation).

Specifically to have the charge bridge activated whenever the generator was running as opposed to only when the voltage gets down to some preset level. The Silverleaf system just doesn't provide the capabilities that I would like.

I have the password into the Silverleaf advanced settings. The red glow is from the Sonoff SV LED showing that the relay is turned on. unplugged) the charge bridge will turn off to ensure that the house doesn’t draw power from the chassis batteries.īelow is a picture of the install. I also have logic such that if the coach looses AC power (ie. When the generator turns off, the charge bridge will turn off. Best of all I can have my RV automation controller active the relay / charge bridge.įor the later, I have automations setup such that if the generator gets turned on, a message is sent to the MQTT server to have the charge bridge engaged. I can point my web browser to the Sonoff SV to turn the relay on. I can push the button the Sonoff SV to manually active the charge bridge. First off, I have Silverleaf with its logic. So now I have many ways that I can enable the charging of my chassis batteries. I installed Tasmota (open source ESP8266 firmware) and configured it to access my MQTT server (think smart home communications hub). The Sonoff SV is installed in the cord reel electrical compartment and is connected to one of the many unused fuse slots. When the relay is turned on, the 12V power is provided as an output which I have connected (along with the Silverleaf output signal) to the White Rodgers solenoid for activation. The Sonoff SV is merely a smart relay that is powered by 12 volts. With a Sonoff SV device (less than $5), I was able to implement a smart switch to charge my chassis batteries at the “right time”.
#Silverleaf battery isolator relay install
So, I decided I would create my own charge bridge controller and install it along side the Silverleaf capability. (Parasitic power draw is a separate issue that I’ve looked into. A few times I have found the chassis batteries below 12.0 volts by morning.
By morning (end of quiet time), my chassis batteries are lower than the 12.4 volts that would kick in charging. If the chassis battery is at 12.5 volts, the charge bridge would not engage and the chassis batteries aren’t able to take advantage of this limited charging time.
This becomes more of an issue when I’m boondocking, as the generator would run before quiet time to charge the house batteries. Thus I would find that my charge bridge would activate several times a day as the voltage on my chassis battery drops. The problem is that 1 hour of charging isn’t long enough to get the chassis battery charged from 12.4 volts (Silverleaf trigger) back up to 12.8+ volts. I’ve tried changing the Silverleaf configurations but to no avail. Silverleaf only activates the charge bridge for 1 hour. When Silverleaf senses a low chassis battery voltage it engages the charge bridge solenoid (assuming the coach has AC power) so that the chassis battery gets charged too. The charge bridge (bidirectional isolator relay) in my Mountain Aire is control by the Silverleaf TM102 module as opposed to an Intellitec BIRD that I believe is installed in the Dutch Star and below models.
