EMP Shield lists it for inverters or charge controllers with an operational range of 90-120 volts. Its label reads Model DC\/90-120V\/W, with +POS on the red lead, -NEG on the black lead and GND on the green lead.\u003c\/p\u003e\n\u003cp\u003eChoose it when the first device after your PV array falls in this voltage range. EMP Shield builds its DC series for standalone solar systems, off-grid cabins and mobile power setups, and for sites such as remote monitoring stations and critical infrastructure. This model fills the 90-120V slot in that lineup, between the 48V and 220-300V models.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\n\u003ch3\u003eEMP Shield DC 90-120 Volt EMP Protection Features\u003c\/h3\u003e\n\u003ch4\u003eSized for the 90-120V Input Range\u003c\/h4\u003e\n\u003cp\u003eEMP Shield offers DC units at eight voltage points, from 12V to 1000V. This one is matched to controllers and inverters that work between 90 and 120 volts, so the protection is set for that part of your system.\u003c\/p\u003e\n\u003ch4\u003eConnects Across the PV Input\u003c\/h4\u003e\n\u003cp\u003eEMP Shield's single solar system diagram shows the DC unit wired across the charge controller's PV input, between the panels and the controller. Red goes to positive, black to negative and green to ground. That placement puts the protection right where the array's wiring enters your equipment.\u003c\/p\u003e\n\u003ch4\u003eThree-Way DC Protection\u003c\/h4\u003e\n\u003cp\u003eThe protection modes EMP Shield lists for its DC units are positive-to-negative, positive-to-ground and negative-to-ground.

The nominal discharge current (In) is 114kA per circuit.\u003c\/p\u003e\n\u003ch4\u003eUnder-One-Nanosecond Shunting and EMP Coverage\u003c\/h4\u003e\n\u003cp\u003eEMP Shield says its SightSpeed technology detects over-voltage and starts shunting it in under a nanosecond. It lists coverage for the E1, E2 and E3 phases of an EMP, CMEs or solar flares, lightning and power surges. MIL-STD-188-125-1, MIL-STD-461G, MIL-STD-464C and RS-105 are the standards EMP Shield reports testing against at Keystone Compliance, at 50 kV\/m and 90 kV\/m. Keystone Compliance, EMP Shield points out, does not endorse products. EMP Shield states that its products carry a Department of Homeland Security listing in the agency's EMP resilience report.\u003c\/p\u003e\n\u003ch4\u003eIP66 Enclosure for Outdoor Sites\u003c\/h4\u003e\n\u003cp\u003eEMP Shield gives this model an IP66 rating and says it can be used outdoors in extreme weather. The gray box mounts with four corner tabs, and its leads exit through a single fitting.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch3\u003eReal-World Applications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOff-grid solar arrays.\u003c\/strong\u003e On an off-grid system, EMP Shield points to the charge controller as the device that sets your choice. If that controller works in the 90-120V range, this unit goes across its PV input.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWind energy systems.\u003c\/strong\u003e EMP Shield groups wind with solar in its list of DC uses.

Pick this single unit for one 90-120V circuit. The Dual version makes sense when two circuits at that voltage need coverage from one box.\u003c\/p\u003e\n\u003ch4\u003eDC 90-120V Unit Versus a Faraday Bag\u003c\/h4\u003e\n\u003cp\u003eA Faraday bag keeps stored electronics shielded while they are packed away. Solar equipment has to be wired and running to produce power. The DC-90-120-W protects the system while it works.\u003c\/p\u003e\n\u003ch4\u003eDC 90-120V Unit Versus a Plug-In Surge Strip\u003c\/h4\u003e\n\u003cp\u003ePlug-in surge strips sit on AC outlets inside a building. They do nothing for the DC conductors running from an array to a charge controller. This unit is built for that DC run.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch3\u003eBuyer Guidance\u003c\/h3\u003e\n\u003ch4\u003eReading Your Equipment's Input Voltage\u003c\/h4\u003e\n\u003cp\u003eEMP Shield's rule is simple. Select the unit by the maximum input voltage of the first device after the PV array. Look up that figure for your charge controller or inverter before you order. If it lands in the 90-120V range, this is your model. If it lands outside that range, the Outbound Power team can help you find the right voltage point.\u003c\/p\u003e\n\u003ch4\u003eWho Should Install It\u003c\/h4\u003e\n\u003cp\u003eThis unit connects to your solar wiring.
