4 Conductor Wiring  - 50 ft with inline fuse-holder & 2 fuses

For lengths in the range 100-300 ft, we can prepare the harness using thicker gauge wires.  As an alternate, consider installing the TM-2030 near the battery/shunt and adding the WF-2030. for remote viewing of battery info.  The WF-2030 has a range of about 200 - 250 ft under ideal conditions.

Why Bogart Engineering

Why does it cost more than the alternatives?

You've probably seen battery monitors for $35–$80 on Amazon. Here's the honest difference:

Bogart TriMetric
Cheap Alternatives
Measurement method
✓ Shunt-based coulomb counting — counts every amp in and out
✗ Voltage estimation — guesses based on voltage alone
Accuracy under load
✓ Accurate even with heavy loads, inverters, and solar input
✗ Voltage sags under load cause wildly inaccurate readings
Battery chemistry support
✓ Fully programmable for any battery — 100+ brand profiles on SC-2030
✗ Fixed profiles that may not match your batteries
Where it's made
✓ Los Gatos, California, USA
✗ China
Who supports you
✓ The engineers who designed it — call or email us directly
✗ Overseas support or no support at all
Warranty
✓ 3 years, backed by a real US company since 1989
✗ 1 year, often difficult to claim
Track record
✓ 35+ years, trusted by the RV and off-grid community
✗ Brand names change constantly

Your battery bank cost $2,000–$20,000. The monitor watching over it should be accurate. That's the whole point.
