The Tri-Metric 2020 meter displays amp-hours, net current flow and battery % full on an LED display.
An LED lights when the battery is charging and flashes when the battery has been fully charged. Another LED flashes when batteries should be recharged or equalized, and during low battery voltage. It also records minimum and maximum voltage, days since batteries were last charged, days since equalized, and total lifetime amp-hours withdrawn from the batteries. The Trimetric can be located hundreds of feet away from the batteries using 4 conductor meter wire.
For 48 V systems or additional lightning protection on 12/24 V systems, use a 48 V adapter with the meter. A shunt is required for operation. Use the 500 Amp shunt if you have a 12 V inverter larger than 1600 watts. Use the 1000 Amp 100mV shunt for systems with stacked SW inverters or where continuous current is over 300 amps. Order shunt separately (listed below).

The TM500A trimetric meter provides easy to understand information such as produced and used DC current. It keeps track of the energy your system has available and energy consumed to ensure adequate reserve power capacity and longevity of your battery bank.
The TM500A is both an energy supply "fuel gauge" and a sophisticated user-option "energy storage computer" that records system characteristics and data. It provides data on all critical system functions, and is capable of monitoring total accumulated charge power from sources such as photovotaic arrays, wind power systems, and generator sets. The TM500A comes with 50' (15 m) of cable, a Deltek 50 mV/500 amp shunt, a prewired cable, and a plug-in adapter board.
Inverter technology takes the raw power produced by the portable generator and using a special microprocessor, converts the energy into a quieter, more consistent and cleaner source of power that more closely resembles the power found in a typical household AC wall outlet.
Discover for yourself the quality, selection,and service that have made Cummins Onan the first choice for convenient, reliable portable power.
Clean, quiet, and neighborhood friendly, all residential generator models run on either natural gas or propane.
Why use an residential generator instead of a portable for home standby emergency power? A permanent residential generator set includes many additional features, including a more complex control system, and usually has more power capacity. It also has a weather protective enclosure that is also designed for sound reduction.

Our Cummins Onan Standby series of portable generators are designed to provide easy to use, safe and reliable portable power for when you need it most.
It doesn't take an emergency to need extra power. With our Cummins Onan Commercial series of portable generators you'll get the required power on demand - up to 12,000 peak watts. These commercial grade generators are ideal for construction, utility and maintenance crews; fire and rescue squads; and rental fleets. The Commercial Portables are also right for the do-it-your-selfers looking for a tough, reliable power source.
The Quiet Diesel Series models are the heavy-duty choice when low noise and low vibration are required. Their revolutionary design makes these generator sets up to 15 dB(A) quieter than other diesel-powered generators, and quieter than most gasoline sets. The unit is totally enclosed, including cooling, muffler and intake systems.
