Review on Samlex America BG 40 Battery Guard by Steve Douglas

Revainrating 3 out of 5

My Samlex BG-40 Battery Guard only works occasionally.

I am using 200W 12V solar panels with a PWM charge controller. I programmed the BG-40 to position 9, ie disconnect at 12V and reconnect at 13V. Often it does not turn off at 12V. When it fails, my Samlex inverter (model PST-300-12) shuts down at around 10.5V and reconnects at 13V.

Pros
  • Easy to use
Cons
  • Some little things
