explanation of standby function)
Standby function
When the solar charging power is lower than the solar controller's own consumption, the
standby function is automatically activated after 30 seconds. This may also occur when the
module is connected to the solar controller for the first time.
Deep discharge protection
The solar controllers of the MPPT series are equipped with deep discharge protection ,i.e. with
battery voltage decreasing to 11V, the solar controller switches the load off automatically. As
soon as the battery is recharged over the solar module, the load switches on automatically.
Overcharge protection
The MPPT solar controller stops the charging process reliably, when the final charging voltage is
reached. This prevents the battery from being damaged by overcharging or heavy steaming.
Desolation function (pulse charging)
Following the regular main charging phase, the solar controller applies pulses to the
battery. This causes sulfate layers in the battery to be dissolved which prolongs the
battery lifetime significantly.
Temperature protective circuit
The MPPT solar controllers switch off the load current, when the temperature inside the device is
too high. The load output continues to function. When the solar controller has cooled down to
normal operating temperature,charging current is reconnected automatically.
Reverse polarity protection
The MPPT solar controllers are protected against incorrect connection to the battery.Ensure
correct polarity when connecting.The solar controller is reset automatically and ready for use
again.
Changing the internal fuse
The solar controllers of the MPPT series are equipped with an internal safety fuse.For changing
the fuse the housing of the solar controller needs to be opened.For this purpose,disconnect the
connected cables and the four screws on the side of the housing.Now it is easy to remove the lid
of the housing and you have free access to the fuse.
Attention: replace the fuse only by a fuse of the same type and rated current! Now close the
housing of the solar controller.
Operation with optional remote controller
Optionally, our MPPT solar controller up to 30A shall with a remote controller function,the
