FAQ

  • What is On-grid inverter?

    On-grid, or grid-tied, means the inverter can generate power when connecting to the grid. When the grid is disconnected or cut-off, the on-grid inverters will stop until the grid is back due to anti-islanding requirements.

    We have single phase from 600W to 8kW, and three phase from 3kW to 150kW. For more details, please refer to this page: https://www.solaxpower.com/x1-boost

  • Can I add battery as energy storage in the future?

    Yes, actually string inverters doesn't have battery management unit integrated. SolaX provides a string inverter + retro-fit + battery storage solution, which makes it possible to extend battery storage to existing string inverter system.

  • Where can I see the solar data?

    You can check the system information on SolaX Cloud via Wi-Fi, LAN or 4G dongle. The data includes voltage(U)/Current(I)/Power(Pin and Pout) of PV side and grid side, energy flow diagram, energy of self-use and export to the grid(*meter or CT installation is required) and other detailed info.

  • Can I see my energy consumption data at night?

    The on-grid inverter can be offline at sunset without enough solar input. If you still want to monitor your system at night, you will need SolaX on-grid inverter with a built-in AC auxiliary power supply(APS) and SolaX smart energy meter/CT to achieve 24 hours energy monitoring.

  • Where excess energy goes when PV array is 200% oversized.

    100% energy is outputed to AC, 100%-165%(X3-Hybrid G4 as an example) is charged to battery. Others will be clipped.

  • Can multiple inverters work in parallel?

    Modbus solution: This solution is applicable to X3-PRO G2 and X1-BOOST G4. With the same series, it supports up to 5 inverters in different power sizes paralleled through Modbus.

    Datahub solution: Datahub is a datalogging device, which can support all SolaX string inverters including X1-MINI G4, X1-BOOST G4, X3-MIC G2, X3-PRO G2, X3-MEGA G2, X3-FORTH and the maximum parallelling number is 60.

  • Do the string inverters support zero export control?

    Yes, the string inverters can achieve zero export control.

  • Can I set the inverters without connecting to the web?

    Yes. You can use local mode or operate on the LCD screem directly.

  • Do all the string inverters have the LCD screen?

    X1-MINI G3/G4, X1-BOOST G3/G4, X1-SMART, X3-MIC G2, X3-PRO G2 equipped with LCD screen by default.

    For X3-MEGA G2 and X3-FORTH,  the LCD screen is optional. 

  • As an installer, what shall I do for commissioning?

    After system installation, there are few steps for commission, such as Wi-Fi and basic inverter configuration. After checking all connections and turning ON all switches, when PV input has exceeded the start-up voltage, the inverter will run into checking and operating status. You can start setting up the Wi-Fi dongle via SolaX Cloud APP to config the connection to monitoring platform.

    Besides, on the APP or the LCD screen you can configure the basic settings easily, including language, date&time, and the safety code according to your local grid standard, and export control if zero injection is required.

  • Where excess energy goes when PV energy is more than needs of loads and battery?

    If you disable 0 export control, excess energy will be injected to grid. If you enable 0 export control, inverter will limite generation power.

  • Does it have to work with network?

    No, but it's better to work online, as we can provide remote support if there is any issue happened.

  • Is there any requirement for on-grid inverter when I use "Micro-grid" functionr?
    It's working for any third-party on-grid inverter. But the power of on-grid inverter should be lower than output power A1-G2 and charging power limite of battery.
  • How to do zero injection control? Do I need energy meter?

    Yes, a meter or a CT is needed for export control(In the on-grid inverter series,only single phase on-grid inverters are compatible with CT,three phase on-grid inverters are not compatible with CT) . Once a meter or a CT is connected, you should configure the inverter via LCD screen(App for non-screen version). Go to setting item 'Export control' to enable meter(or CT) and then confirm how much power to inject to the grid. If you want zero injection, you just need to set the value to 0.

  • Do you have the compability list of the pocket and the inverters
