Generator Panel
The generator panel is easy view with the door closed through the window or open as you see here. It is easy to quickly see engine and alternator status with the indicator lights or gauges. Operation is monitored by a generator controller that takes care of automatic starting and stopping. Low oil, high temperature and some other fault conditions such as battery charging are also monitored.
Simple easy to read panel showing both the digital controller and its status lights as well as the voltage,
frequency, amp meters, water temperature, oil pressure, battery voltage and hour meter.
