Important Safety Instructions This manual contains all safety, installation, and operation instructions for the XTR series Maximum Power Point Tracking (MPPT) solar charge controllers. Safety instructions for installation Read all the instructions and warnings carefully in the manual before installation.
1 General Information 1.1 Overview Thank you for choosing the Photonic Universe XTR series MPPT solar charge controller. This product features a new highly stable and efficient system architecture. It also includes a built-in Bluetooth module, allowing installers and users to easily read and adjust parameters via the mobile app.
2. To enable the constant voltage output function, ensure the input power is consistently higher than the output power. If the input power is lower than the output power, the controller will switch between ON and OFF states intermittently due to the under-voltage protection. 3.

As per Figure 1.2, MPPT technology will ‘boost’ the battery charging current (amps) by tracking the MPP. Assuming 100% conversion efficiency of the solar system, the battery current will increase in line with the following formula: Normally, the V is always higher than V .
Some MPPT solar charge controllers are unable to accurately track multiple MPP points. As a result, they lock on to an incorrect point and work with reduced efficiency. This solar charge controller features special MPPT technology that can handle multiple MPP points and track the true MPP point quickly and accurately, improving system efficiency and avoiding energy wastage.

2.3 Wire Size The wiring and installation methods must conform to all national and local requirements. PV Cable Size Since PV array output can vary due to the PV module size, connection method or light exposure, the minimum cable size can be calculated based on the maximum current (Isc) of the PV array. Please refer to the value of Isc in PV module specification.

If your system has an inverter, in this Battery mode you should connect the inverter CAUTION to your battery directly. Never connect the inverter to the load terminals. 1) Connect components to the charge controller in the sequence 1-2-3 as shown on the diagram above and pay particular attention to the polarity (“+”...
If a temperature sensor is not connected, the controller will assume a default temperature 25ºC. 2) (for 20A-40A controllers) use an optional Photonic Universe surface mounted (CB series) or recess mounted (CBR series) DC circuit breaker with overcurrent protection instead of a battery fuse (30A, 40A,...
3) Connect an optional Remote meter with 5m cable (product code MT52). The meter displays system information and allows parameter setting and self-diagnostics (see Annex II for details). 4) Connect an optional USB to RJ45 adapter with 1.5m cable (product code PTR-USB) to link the controller to a PC for monitoring and programming using Solar Station software (see Annex II for details).

*The SYS value can only be modified under the non-lithium "USE" type. The SYS value can be modified if the battery type is Sealed, Gel, or Flooded before entering the "USE" type. The SYS value cannot be modified if it is a lithium battery type before entering the "USE" type. For the no-battery application, the SYS value must be set to the nominal input voltage of the inverter or another load / device connected to the battery terminals of the controller.

3) Setting the battery parameters by an app via an external Wi-Fi module Connect an optional Wi-Fi dongle (product code EBOX-WIFI) to the RS485 communication port of the controller. The charging parameters can be set using the mobile app after setting the battery type to "USE". This option also allows remote monitoring.
