No built-in Bluetooth. External accessories are required, and the device supports one-to-one monitoring

The 'BLE' model has built-in Bluetooth, allowing parameter reading and modification through the app.
Additionally, it can meet various monitoring requirements by adding communication accessories such as MT52, PC communication cable, or WiFi module via the COM port.

Note: Models with built-in Bluetooth do not require additional communication accessories. They allow real-time parameter reading and modification through the app, making the application more convenient. Also, allow more then one monitoring equipment work toghther at same time.

No Constant Voltage Output Function; PV cannot directly supply loads.
During the solar charging process, if the BMS of the lithium battery cuts off the output or disables charging, the controller's battery terminal may experience overshoot voltage (for 12V/24V models, whether it's a 12V or 24V system, the overshoot voltage can reach up to 35V; for 12V/24V/48V models, it can reach up to 70V), potentially leads to unstable load supply voltage, even damages the load equipment.

When operating Constant Voltage Output (without batteries or battery protection cutoff), if the PV energy is sufficient (PV real-time power generation > peak load real-time power), the controller's battery terminal can directly supply the load.
The output voltage protection value will vary depending on the set voltage level: 12V system ≤ 17.6V, 24V system ≤ 31V, 48V system ≤ 61V, to prevent excessive overshoot voltage that could damage the load or lithium battery protection board.

Note: Constant Voltage Output Function allows for the expansion of system applications while ensuring maximum system stability during continuous operation. It also provides comprehensive compatibility with various lithium batteries, eliminating worries about unstable load supply voltage or damage caused by the internal protection of lithium batteries.

No Output Overcurrent Protection: If there is a load short circuit fault on the battery side or if large impact loads such as inverters are activated during the PV activation oflithium battery process (after the lithium battery BMS triggers over-discharge protection), the controller may be damaged due to excessive surge current.

Having Output Overcurrent Protection prevents controller damage caused by load short circuit faults on the battery side or the activation of impact loads during PV activation of lithium batteries.

Note: Comprehensive protection functions make the product operation safer and more reliable.

No function

Can disable COM port communicate function via LCD, further reducing device self-consumption.
Note: This setting can only be done via the LCD, and once finish set, the built-in Bluetooth module and external COM port communicate function will be disabled

Note: Customers can enable or disable the communication function as needed, extending the system's standby time to over 1.7 times

Power consumption for this series：
≤30mA/12V (minimum 14mA);
≤16mA/24V(minimum15mA);
≤13mA/48V

In the absence of load output, there will has audible low-frequency noise

When enable communication, series self-consumption：
≤15mA/12V (minimum10mA);
≤9mA/24V(minimum7mA);
≤7mA/48V

When disable communication, series self-consumption：
≤8mA/12V;
≤6mA/24V;
≤5mA/48V

Ultra-quiet design，operates more quietly

Note：In the case of communication being disabled，the system's standby time can be extended to more than 1.7 times. Ultra-silent design for quieter indoor use.

9V~17V/12V system（24V system*2,48V system*4）

Overvoltage disconnect voltage：9V~17V/12V system；
Other charging voltage setting range：9V~15.5V/12V system（24V system*2,48V system*4）

No max. charging current limit setting function

Max. charging current setting range: 1A toRated charging current*(can only set by PC software or APP)

1.The explanation for voltage setting range 9V~15.5V: Due to the XTRA G3 series have the ability (constant voltage output function) to connect the load directly to battery side, if the load on battery side such as low-frequency inverters which has relatively large ripple voltages, this ripple voltage will superimpose on the controller's charging voltage, affecting the overshoot voltage value and potentially triggering inverter protection, will detrimental to the system.
2.The current limiting function mainly solves the problem of mismatched batterie capacity and photovoltaic module power.

Four modes: Manual Mode, Light (ON/OFF) Mode, Light ON + Timer Mode, and Real-time Control Mode.

Six modes: Manual Mode, Light ON/OFF Mode, Light ON/OFF + Timer Mode 1 (night on and day off), Light ON/OFF + Timer Mode 2 (day on and night off), Real-time Control Mode, Always ON Mode

Note: Increase load control mode to meet more application scenarios,such like some client ask the load work at day time and stop at night time.

MT50：Compatible with SV2.18 and above

MT52：It only adds two temperature settings for Lithium battery low temperature protection on top of the latest version of MT50.

CLASS B: Underloaded testing, doesn’t meet the certification standards for CLASS B in practice.

60V/100V：CLASS B， full-load testing, fully compliant with certification standards.150V：CLASS A，full-load testing, fully compliant with certification

Note: ①MT52 encompasses all the functions of MT50, and both have identical appearances. SV2.20 and above versions of MT50 can also be used for the G3 series. ②Reason for introducing MT52: R&D considers that older versions of MT50 (SV2.18 and below) incompatible with the G3 series may still be in circulation in the market.
