ME-BMK Battery Monitor Kit - No Shunt

To ensure your batteries perform satisfactorily and have a long life, they need to be properly maintained and charged. If you're using a Magnum Energy ME, MS, MS-AE or RD inverter, monitoring your battery bank is easy with Magnum Energy's Battery Monitor Kit (ME-BMK). This kit acts as a “fuel gauge” for your batteries, monitoring their state of charge (SOC) and then providing this information in an easy-to-understand display via the ME-RC remote. With accurate SOC readings, you can avoid unnecessary battery recharging, saving on fuel and long-term maintenance costs.

There are several other monitoring devices on the market that measure different aspects of a battery bank. The DC Voltmeter measures Open Circuit Voltage. It is not completely accurate and requires the batteries be at “rest” when in use. A hydrometer is another device that measure the concentration of battery electrolyte in each individual cell and compare the readings with the OCV values from the battery manufactures. An amp-hour meter is an electronic measuring device that uses a precision shunt to calculate the amp-hours going in (charging) and coming out (discharging) a battery. This meter tracks the amp-hour usage and compares it against the amp-hour capacity of the battery to determine its charge condition.

The Magnum Energy Battery Monitor actually combines the advantages of these devices with additional information such as monitoring battery temperature and calculating battery efficiencies to provide an easy and accurate means to determine the battery’s State of Charge (SOC) condition.

**BMK requires 2 Amp DC fuse from any autopart store.

About Magnum Energy

When Xantrex bought Trace, a few of their key people started Magnum Energy. Established in 2002 in Everett, Washington, Magnum Energy went on to make great strides in the renewable energy field with their high-quality inverters.
A company that doesn't just rest on their brand name, Magnum Energy's research and development team is constantly pushing the boundaries of inverter technology. They pioneered the technology behind power factor corrected battery chargers, which is in each and every one of their inverters. This innovation is the most efficient way to charge batteries. Magnum Inverters save you the time, money and hassle it takes to gas up your generators. Another nice feature of Magnum Energy inverters (whether they are 120 VAC or 240 VAC) is that they can accept 120 or 240 VAC power input to help charge the batteries without the use of a transformer.
Magnum Energy has also made advances with AC Coupling, which allows a solar power grid-tie system to work with a backup battery system that can be charged even during grid black outs. This is a perfect add-on for folks who want to include a battery back-up package to their pre-existing grid-tie system. Read more about AC coupling here.
Magnum Energy inverters are also good-looking, safe, easy-to-use and American-made. Wholesale Solar was one of the first renewable energy companies to distribute Magnum Energy. We carry all Magnum Energy Inverters for RV, Marine, or Back-up power. We have also have teamed up with Magnum Energy to create to power centers called the Mini-Magnum Power Centers. The MS4024PAE and the MS4448PAE Power Centers are perfect for offgrid living or AC coupling with a grid-tied system anywhere.
