Description

The SH-500-50 is a current shunt that is used by the the TM-2030 battery monitor by Bogart Engineering to measure your RV’s electricity usage. A shunt is the component that measures how much current flows into or out of the battery bank. The SH-500-50 shunt is recommended for most medium size RVs with electrical loads not exceeding 400 A. In most typical RVs the greatest loads develop when a microwave is used. Typical RV microwaves are rated at 900 – 1,200 W of cooking power and 1,000 – 1,500 W of power consumption, so they will pull approximately 100-120 A from 12 volt batteries. Therefore, a 500 ampere shunt is the appropriate size. If you never use a microwave or any other high power device, a 100 or a 200 ampere shunt may be sufficient. A smaller shunt can provide finer current resolution, which can be fun to watch and overanalyze.

However, for practical and wide range use, a 500 A shunt is probably the most versatile.

For over 25 years, Bogart Engineering has been making battery monitors that give you insight into your battery storage systems. If you depend on batteries for power in your off-grid cabin, RVs, campers or boats, Bogart monitors show 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.
