About Us



Working with expensive Lithium battery banks?

We are your sole-source provider for high current, bi-directional, solid state low voltage disconnects capable of currents up 600 amps continuous duty at 12 or 24 volts.

With with up four levels of undervoltage and overvoltage, timers, short-circuit protection, override and low power sleep mode, all in a power-dense programmable package, POWER-GATE bi-directional DC relays are perfectly suited to compliment and protect your off-grid lithium battery storage system. 

POWER-GATE’s line of Single and Dual Rectifiers enable you to control your DC resources at peak efficiency. With no heat sinking and no airflow required, POWER-GATE devices are designed to provide ultimate peace-of-mind; you’ll not find a superior isolator on the planet. That same attention to engineering detail goes into the entire POWER-GATE family, including Low Voltage Disconnects, OR’ing Diodes, and Solid State Relays.

It’s no mystery why high performance battery manufacturers recommend the use of POWER-GATE devices: when switching or isolating DC power, efficiency is key. POWER-GATE enjoys industry leading sub-100 micro-ohm resistance at current levels our competitors can only aspire to.

POWER-GATE is equally at home on a sailboat, a million dollar Marathon Coach, or a rural off-grid homestead.
