What kind of batteries is this controller suitable for?
The controller is suitable for use with 12/24V deep cycle batteries of the SLD/AGM; GEL; Flooded; Li
What wire is needed for this controller?
This controller is suitable for wiring gauges 8AWG, the cable length should be taken into account when selecting the cable
What is the maximum number of PV modules that can be connected to this controller?
The maximum solar voltage that can be connected is 95 V and the maximum solar power is 400W for 12V. In the case of 24V systems, the maximum PV power that can be connected is 800W. It is best to use panels of the same size and not to exceed the input voltage & power limits.
Is there anything to be aware of when installing wiring for this controller?
Ensure that the controller is mounted vertically with a 150mm clearance for proper heat dissipation. When wiring the controller connect it to the battery first, followed by the solar panel.
Is it necessary to connect the temperature sensor on the controller?
Non-lithium batteries need to be connected to a temperature sensor in order to protect batteries from high or low temperature through temperature compensation with timely adjustment of charging voltage. Note: No temperature compensation in Li mode, there is no need to connect a temperature sensor for lithium batteries.
Is this controller waterproof?
The waterproof rating of this controller is only IP32, so it is not waterproof
Does the controller have an electrical protection function?
This controller is equipped with electrical protection functions, such as: over-voltage protection, reverse connection protection, over-power protection, etc.
How to choose a fuse when wiring this controller?
The fuse on the PV access side needs to be calculated according to the PV current of the input port (total PV current * 1.56), the recommended fuse size for the output port is 40A
What is the self-consumption of the controller?
This controller has a self-consumption of ≤ 100mA for 12V\≤ 58mA for 24V
Can I use the DC HOME APP to monitor this controller?
Yes. This controller can be used with the BT-1, so you can monitor the controller's data via the DC HOME APP.
How to set your own charging parameters on the DC HOME App?
First change the battery type to USER mode on the DC HOME, then change the charging parameters on the DC HOME.
Can multiple controllers be used to charge the same battery?
It is possible to use multiple controllers to charge the same battery, but make sure that the battery can withstand the charging current provided by multiple controllers
Does this controller have a parallel function?
No, it doesn’t.
What are the operating environment requirements for this controller?
The controller is designed to operate in an environment that is protected from direct sunlight and ventilation and has an operating temperature range of -35°C to 45°C.
What can its LOAD port be used for?
The load port can only be connected to DC devices and requires the voltage of the device to be the same as the battery voltage, and the load port can only supply a maximum current of 20A.
Can multiple units of this product be connected in parallel to charge the battery?
Yes, but the following factors need to be considered: a. Due to device accuracy errors, there might be a situation where two devices detect different battery voltages, leading to inconsistent charging statuses between the two devices. This is especially common during the low-current charging stage and should be considered normal. b. When multiple devices are simultaneously charging the same battery pack, it's important to ensure that the sum of the charging currents from all devices does not exceed the maximum charging current supported by the battery pack.
