NOTE: Regardless of DIP 7 setting, manual
EQ can be initiated using the on-board meter
command, Start Equalize. For non-meter
versions, DIP 7 only enables or disables auto
equalization; manual EQ is not available.
To select pre-configured settings (all models):
• Configure DIP Switches 4, 5, and 6 to one of the
pre-configured selections shown below.
See the EcoBoost Installation, Operations, and Maintenance Manual for additional information/guidance.
To select customized settings (metered versions only):
• Set DIP Switches 4, 5, and 6 to Custom and use the
interface on the meter to configure the settings.
NOTE: The EcoBoost MPPT (metered models only) can be programmed to accommodate a wide range of charging parameters.
Consult the battery manufacturer for optimal battery charging settings.
