EMP Shield 1000 Volt DC Protection For Large Solar Applications

EMP Shield 1000 Volt DC Protection Adds EMP, Lightning And Surge Protection To 1000V Solar Equipment

The EMP Shield DC/1000V/W is the 1000V model in EMP Shield's DC series, whose voltage options run from 12V up to 1000V. Its EMP Shield product name ties it to solar and wind systems. It's a single shield with one protected circuit, three leads and one green ON light on the label.

This model is for solar owners and installers whose equipment sits at the 1000V point. To size a shield, EMP Shield looks at one figure, the maximum input voltage of whatever device the PV array feeds first. That device tends to be a charge controller when the system is off-grid and an inverter when it's tied to the grid. EMP Shield designs the DC series to help that equipment, plus energy storage and connected devices, stay safe and operational through EMPs, lightning strikes and power surges.

EMP Shield 1000 Volt DC Protection Features

Built For The 1000V Voltage Point

EMP Shield offers its DC shields at set voltage points, and 1000V is the top one on its list. Matching the shield to your equipment's voltage is how EMP Shield sizes protection for a system.

One Circuit With Three Labeled Leads

The label marks +POS as red, -NEG as black and GND as green. In EMP Shield's single solar drawing, red goes to positive, black to negative and green to ground, so the hookup has three wires in all.

114kA Nominal Discharge Current

Per circuit, the DC series carries a 114kA nominal discharge current (In) rating from EMP Shield. For surge capacity, EMP Shield's series figure is 228kA per phase.

SightSpeed Response

Less than one nanosecond is EMP Shield's stated time for its SightSpeed technology to begin shunting an over-voltage event. The excess energy is routed away from the 1000V device the shield is connected to.

Protection Between Every Conductor Pair

EMP Shield lists three protection modes for this series. They are positive-to-negative, positive-to-ground and negative-to-ground, so each pairing of the three conductors is accounted for.

IP66 Housing From A Kansas Maker

EMP Shield rates this housing IP66 and describes its DC units as usable outdoors in extreme weather. On the label, "Veteran Owned Kansas Company" lines up with EMP Shield's word that it builds its units in Kansas, USA.

Real-World Applications

Solar And Wind Systems. Off-grid solar and wind energy systems lead EMP Shield's list of DC uses, and this model's name points to both. A system whose first device after the array sits at the 1000V point is the intended match.

Grid-Tied Solar Inverters. For grid-tied solar, the inverter is usually the device EMP Shield tells you to check. If that inverter's maximum input voltage is 1000V, this is the EMP Shield model that lines up with it.

Battery Backup For Business And Industry. EMP Shield's DC use list covers backup power at commercial and industrial sites too. When that backup equipment runs at 1000V, this shield fits the voltage.

Practical Comparison

EMP Shield 1000V Single Versus Dual 1000V

EMP Shield also offers a Dual/DC/1000V/W, which puts two DC shields in one device to save space. This single version is for a system with just one 1000V device to protect. Choose the dual only if you have two matching 1000V inverters or charge controllers.

EMP Shield 1000V Versus The 600V Model

EMP Shield's next voltage point down is 600V. Both share the series ratings, so the decision rests on your first device's maximum input voltage. Use the 1000V model when that device sits at 1000V.

EMP Shield 1000V Versus A Plug-In Power Strip Surge Protector

A plug-in strip only serves AC equipment at a wall outlet. It never touches the DC wiring coming off a 1000V solar array. The 1000V shield connects across that DC wiring at the first device after the panels.

Buyer Guidance

Choose By The First Device After The Array

Look up the maximum input voltage of the charge controller or inverter your PV array feeds first. If it's 1000V, this unit matches. For a figure that lands between two of EMP Shield's voltage points, check with the Outbound Power team first.

Installing A 1000V Shield

EMP Shield's single solar installation drawing shows the panels feeding a charge controller and battery, with the shield connected across the charge controller's PV input and its green lead run to ground. A licensed electrician should handle a 1000V installation, and EMP Shield's $25,000 connected equipment policy counts a licensed electrician install among its conditions.

This May Be A Good Fit If

• Your first device after the array has a 1000V maximum input
• You protect one charge controller or inverter at that voltage
• Your solar or wind equipment faces extreme weather
• You'll have a licensed electrician install it

Common Questions

Is There A Dual Version Of The 1000V Model?

Yes. EMP Shield offers Dual/DC/1000V/W next to this single DC/1000V/W, with dual versions at every voltage point of the series.

What Testing And Listings Does EMP Shield Cite?

Keystone Compliance is where EMP Shield says it tested to RS-105, MIL-STD-464C, MIL-STD-188-125-1 and MIL-STD-461G, though EMP Shield adds that Keystone Compliance does not personally endorse any products. EMP Shield also states it is listed by the Department of Homeland Security. The threats it names are E1, E2 and E3 EMP phases, CMEs, lightning and power surges.

Which Lead Connects Where?

Red is +POS and goes to positive. Black is -NEG and goes to negative. Green is GND and goes to ground, as the label and EMP Shield's single solar drawing both show.

Is The 1000V Shield Covered By A Warranty?

Yes, on EMP Shield's terms. A 10-year limited warranty on materials and workmanship has EMP Shield repairing or replacing a defective shield. A shield ruined by lightning can be exchanged for $50 after the destroyed unit reaches EMP Shield. Damaged connected electronics fall under a different EMP Shield policy capped at $25,000, which requires, among other things, a claim within 30 days.

What's Included

• 1 x EMP Shield DC 1000V Unit

Protection Sized For 1000V Solar Equipment

The EMP Shield 1000 Volt DC Protection unit gives a 1000V charge controller or inverter its own EMP and surge protection, wired across positive, negative and ground. For help confirming your equipment's voltage or choosing between the single and dual 1000V models, contact the Outbound Power team.
