AIMS Power Battery Isolators & Voltage Sensitive Relays
AIMS Power Battery Isolators & Voltage Sensitive Relays
AIMS Power has built a strong reputation over more than two decades as a leader in off-grid and renewable energy power management. While the brand is widely recognized for its inverters and solar products, its battery isolators and voltage sensitive relays reflect the same engineering philosophy: protect your power system intelligently, automatically, and reliably — whether you're on the road, on the water, or living off the grid.
Solid-State Protection for 12V DC Systems
At the heart of AIMS Power's offering in this category is their Battery Voltage Regulator and Isolator, engineered around solid-state technology. Rather than relying on mechanical switching alone, this design uses electronic monitoring to keep your system safe. The unit continuously watches input voltage, and as long as levels remain within the safe operating window, power flows normally to your loads. Step outside that range — either too low or too high — and the unit acts instantly to cut off output and shield your batteries from damage.
This approach is well-suited to the diverse and demanding environments where AIMS Power products are deployed: vehicles, RVs, boats, wind systems, hydro systems, and any 12V off-grid application.
Lithium Battery Compatibility
One of the standout features of AIMS Power's isolator and regulator products is their compatibility with modern lithium battery chemistries. Mixed battery setups — pairing lithium with lead-acid, for example — are increasingly common in mobile and off-grid systems, but they introduce the risk of overcharging. AIMS Power addresses this directly: the regulator prevents lithium batteries from overcharging when used alongside alternators or other charging sources, making it practical to use lithium in virtually any 12V application.
Dual Sensing Smart Isolator Technology
AIMS Power also offers a Dual Sensing Smart Battery Isolator line, exemplified by the 300 Amp model. This design monitors both the starting battery and the auxiliary battery simultaneously. If either battery exceeds 13.2 volts — roughly an 80% state of charge — the isolator automatically connects them, allowing charge to flow between the two. When the overall system drops back below 12.7 volts, the solenoid opens and keeps the starter battery isolated from the auxiliary, so you're never left stranded with a dead starting battery. Because the system is voltage-based and fully automatic, no ignition wire connection is required, simplifying the installation process significantly.
Built-In Safety and Auto-Reset
AIMS Power's isolator and regulator products also include layered overcurrent protection. When current exceeds the rated threshold for a sustained period, the relay disconnects to prevent damage. Once conditions return to normal, the unit resets automatically after a short delay, resuming protection without any manual intervention. This combination of automatic connection, disconnection, and self-reset makes AIMS Power's battery management products a reliable fit for systems that need to operate unattended — from solar-charged cabin setups to work trucks and fleet vehicles.
Simple Installation
A compact 2-wire terminal configuration means these units can be integrated into most standard 12V wiring without complex rewiring. Whether you're an experienced installer or a motivated DIYer, the straightforward design reduces setup time while still delivering professional-grade battery protection.
