Isolated SmartSolar MPPT RS

2.3. Setup options

Adaptive three step charging
The SmartSolar MPPT Charge Controller is configured for a three step charging process: Bulk – Absorption – Float.
A regular equalization charge can also be programmed.
Bulk- During this stage the controller delivers as much charge current as possible to rapidly recharge the batteries.
Absorption - When the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode.
When only shallow discharges occur the absorption time is kept short in order to prevent overcharging of the battery. After a deep
discharge the absorption time is automatically increased to make sure that the battery is completely recharged.
Additionally, the absorption period is also ended when the charge current decreases to less than 2A.
Float - During this stage, float voltage is applied to the battery to maintain a fully charged state.
Optional external voltage and temperature sensor
Wired connections are available for battery voltage and temperature sensing. The Solar Charger uses these measurements to
optimize its charge parameters. The accuracy of the data it transmits will improve battery charging efficiency, and prolong battery
life.
The Smart Battery Sense and other VE.Smart networking features are not currently supported by the MPPT RS.
Remote on-off input
On/off control by a VE.Bus BMS when charging Li-ion batteries.
Remote L functions as 'allow to charge' in case lithium battery is selected and remote H functions as 'allow to discharge' and can
pass this function to a compatible inverter. Use miniBMS for the RS with Victron lithium batteries.
Programmable relay
Can be programmed (with a smartphone) to open or close on an alarm, or other events.
