The Sol-Ark EMP resistant inverter will protect against solar flares, lightning, or electromagnetic pulse from weapons detonation.
NTS Testing and Certification Services verified the Sol-Ark Inverter to withstand more than 100KV/m EMP. 100KV/m is 100,000 Volts per meter of Electromagnetic Pulse. That is an intense pulse.
The Sol-Ark equipment was successfully tested to withstand MIL-STD-461G specifications of greater than 50KV/m.
The Sol-Ark inverter was tested to 100KV/m, the limit of NTS test equipment, which is double the certification requirement.
The same Sol-Ark inverter easily survived 140 individual electromagnetic pulses coming from 3 axis of rotations - with NO DAMAGE to the inverter.
Appliances connected to the Sol-Ark inverter are also protected! The EMP Suppression system protects the Sol-Ark inverter, the solar panels, and electronic appliances plugged into the Sol-Ark system.
4.3.1 Test Facility
All testing occurred within a shielded semi anechoic enclosure, located in Plano, TX. The chamber is lined with anechoic Radio Frequency (RF) absorbing cones on the walls and the ceiling. Peripheral equipment was located outside the shielded enclosure. All power leads entering the shielded enclosures were routed via electromagnetic interference filters to provide at least 80 dB of attenuation above 10 kHz when measured in accordance with MIL-STD-220B. Interconnecting cables were routed via feed-through ports mounted on the enclosure. Shielding effectiveness to electric fields and plane waves of this EMI test chamber exceeded 80 dB from 14 kHz–10 GHz, and 60 dB from 10 GHz–40 GHz.
The anechoic RF absorber material shown in Figure 4.3-1 (carbon impregnated foam pyramids) is used when per- forming electric field radiated emissions or radiated susceptibility testing inside a shielded enclosure. It is intended to reduce reflections of electromagnetic energy and to improve accuracy and repeatability.
Susceptibility test signals for RS105 are pulse modulated (on/off ratio of 40 dB minimum) at 1 kHz rate with a 50% duty cycle.
Thresholds of Susceptibility
When susceptibility indications were noticed in EUT operation, a threshold level was determined when possible, and where the susceptible condition was no longer present. Thresholds of susceptibility were determined as follows:
When a susceptibility condition was detected, the interference signal was reduced until the EUT recovered.
The interference was reduced by an additional 6 dB.
The interference signal was gradually increased until the susceptibility condition reoccurred.
The level, frequency range of occurrence, frequency and level of greatest susceptibility, and other test parameters, as applicable were recorded.
