Magnum Energy ME-BMK Battery Monitor
The ME-BMK (Battery Monitor Kit)* from Magnum Energy gives you a “fuel gauge” type of meter for your battery bank. It monitors the battery bank and reports the percentage state of charge, real time amps, voltage, amp-hours in/out, and the minimum/maximum DC volts. The ME-BMK includes the sense module, sense and communication cables, and a 500-amp shunt.
The ME-BMK-NS requires a Magnum inverter with a "Network" port and a ME-RC (revision 2.0 or higher) or ME-ARC remote control.
