How to Start an Equalization Charge with the ME-ARTR

This episode in the Magnum video series is designed to help guide you through the ME-ARTR revision 4.0 in order to start an Equalization charge. Equalization is a higher voltage charge that helps de-sulfate Lead Acid batteries. Performing an Equalize charge on batteries other than liquid lead acid or certain AGM types could permanently damage them. Check with your battery manufacturer to see if equalizing is right for your battery bank and refer to your owner’s manual for more in-depth safety information. Make sure you have the proper amount of distilled water in the batteries and keep them well ventilated, as the higher charge during Equalization can cause gassing. Finally, it is generally recommended to disconnect DC and AC loads while Equalizing so that no damage is done to the DC loads and so the AC source can focus on Equalizing the batteries without having to worry about any load demand.

You should have already programmed your Equalization setpoints when you setup your battery charging parameters. Your inverter must actively be in Float or Full charge in order to initialize an Equalization charge. Press and hold the Charger On/Off button for 7 to 10 seconds. The status will change from Float to Equalizing. The inverter will now Equalize your batteries for the amount of time you programmed in the Charger setup. Now that you have successfully started Equalizing your batteries, you can press Meter to return to the Main Screen. Once Equalization is complete, your system will automatically return to Float charge.
