The TriMetric TM-2030 is the most accurate battery monitor for RVs, off-grid homes, and boats — engineered with shunt-based precision that voltage-only monitors can't match.
Every combo ships with everything you need for a complete install — shunts, wiring harness, cables & temperature sensor included. Save more with every product you add.
Already have some components? Add what you need. Every TriMetric product is compatible with the others.
Surface Mount
White surface-mount enclosure (3×4¼×1¼"). Mounts to any wall with screws. Ideal for RVs, trailers, and van builds.
Flush Mount
Flush-mount panel (4½×4¾") fits standard double-gang electrical boxes. Operationally identical to RV version — different form factor only.
Solar Charger
Precision 4-stage PWM solar charge controller. The only charger on the market that uses amp-hour based charge termination to prevent battery undercharge and sulfation.
WiFi Remote
Add wireless monitoring to your TM-2030. See live battery data and adjust all settings from any smartphone, tablet, or laptop — no app required.
Required for TM-2030 operation. High-accuracy shunts in 500A/50mV (for most systems) and 100A/100mV versions. Already included in all kits.
Pre-made 4-conductor harness with inline fuse holder and fuses. Required for TM-2030 installation. Available in 35ft and 50ft lengths.
Measures actual amperage through a precision shunt — far more accurate and stable than Hall-effect sensors used by competitors like Victron, Renogy, and Aili monitors.
The only monitor on the market that shows replaced charge percentage — letting you see whether you're under- or over-charging after each cycle. Critical for battery longevity.
When paired with the SC-2030, you get the only solar charging combo that uses amp-hour counting to terminate charging — preventing sulfation and extending battery life.
TriMetric monitors installed 35 years ago are still in daily operation. We support legacy products with firmware updates and still answer calls from customers with original units.
Questions answered by the scientists and engineers who designed the products. Comprehensive manuals, application notes, and an FAQ written by people who actually know the hardware.
Every TriMetric product is engineered and manufactured in California. No offshore assembly, no compromises on component quality. American engineering you can trust for decades.
Whether boondocking in an RV, running a solar cabin, or cruising offshore — the TriMetric system adapts to your power setup.
The #1 choice for full-time RVers. Know your hours of runtime before you need to move or charge.
Manage solar + battery banks in remote homes with the precision that protects your investment.
Monitor house banks reliably. Compact, reliable engineering built to survive demanding environments.
Compact, mountable, and durable. Perfect for custom vans and overland rigs with LFP or AGM banks.
Optimize solar self-sufficiency with granular charge tracking and amp-hour based controls.
Unlike most monitors, the TM-2030 supports virtually every battery type — lead-acid, lithium, and nickel-iron. The SC-2030 includes programmable charging profiles for all chemistries.
"The Trimetric was always high on my list. It seems to be widely accepted as one of the best. When paired with the SC-2030 you get very fine grain control over how the battery bank is charged. Price was also a consideration — you can't beat it."
"Their communication is always great — quick to respond. They did more than I expected to sort out my setup. SO BOGART has until recently been the GOLD STANDARD for monitoring. They will actually answer not only your email but your phone calls."
"I've had Bogart Engineering products installed for years and they have worked perfectly. The TriMetric is an accurate and reliable battery monitoring tool. The Bogart combo gives you complete control over every aspect of your charging."
Join thousands of RVers, off-gridders, and boaters who depend on TriMetric every day.
