Essential Products for RV’s and Off-grid Battery Power Systems




For over 30 years we’ve made shunt based battery monitors and solar chargers that give you insight into your battery storage systems. Our products are manufactured in the US, in our California/Silicon Valley facilities.

If you depend on batteries for power in your off-grid cabin, RVs, campers or boats, our battery gauges are indispensable. They show you how full your batteries are, if charging sources are still charging like they used to, how fast your loads are drawing power, and to check whether your batteries are still storing energy as they should.

If you use solar panels in your RV or truck camper, consider our SC-2030 Solar Charge Controller. Combined with our Trimetric TM-2030 Battery Monitor, the SC-2030 offers complete control over charging of the RV batteries, including automatic daily mini-equalization, to extend the life of your flooded cells, AGM or lithium LFP batteries.
