SURGE PROTECTION DEVICES
Highly recommended as protection for your valuable power system are the Surge Protection Devices (SPD's) or lightning protectors from MidNite Solar and OutBack Power.
MidNite Surge Protection Devices for Lightning Protection
The SPD is offered in three different voltages to maximize the required protection level. Protection is achieved by reducing the clamping voltage to a safe level that your system can sustain without damaging any electronics in the system. The MNSPD is designed to clamp a 115,000 amp surge! Blue LED’s provide visual indication of operation from a distance.

OutBack Power Surge Protection Devices for Lightning Protection
OutBack Power’s FLEXware Surge Protector is the only choice when you want to protect your FX Series Inverter/Charger from the harmful effects of transient power surges. Ease of installation and seamless integration make it the obvious addition to your OutBack Power system.FW-SP-ACA AC Surge Protectection Adaptor 390Vac / 150VdcFW-SP-R Surge Protector Replacement
GROUND FAULT PROTECTION
A Ground Fault Protection device (GFPD) detects a ground fault current, interrupts the flow of the current and provides an indication of the fault. MidNite Solar, Morningstar and OutBack Power offer solutions.
MidNite DC Ground Fault Protection Devices
MidNite’s breakers are rated to break the full rated load at the rated voltage repeatedly, with NO DAMAGE. Always use a properly sized breaker for disconnecting.

Morningstar DC Ground Fault Protection Devices
When a ground fault is detected, Morningstar’s GFPD breaks the circuit on both the positive and the negative legs and ensures interruption of the ground fault current.GFPD-150V60 amp 150V maximum PV voltageThe Morningstar GFPD supports a wide range of battery voltages (12V, 24V, 36V, 48 Vdc nominal systems) and many advanced designfeatures for simplified installation. The GFPD is equipped with:• A bi-color LED to provide operating status, GFPD events and module or wiring faults• A notification and alarm feature, providing an extra safety measure:• Detects a ground fault condition• Indicates when the PV system’s battery bank voltage is getting critically low• A simple test button feature for an installer to press to simulate a trip event when checking wiring and switchesGFPD-600V50 amp 500V maximum PV voltageMaintains the integrity of earth bond for battery and loads• Trips at lower fault current with greater accuracy• Breaks both conductors in the faulted circuit and completely isolates PV source circuits• Provides design flexibility to meet a wide range of configurations:• Positive and negative ground• Large and small arraysasis.
