The Growatt MID TL3-X and MID TL3-XL series photovoltaic inverters are designed to convert direct current generated by photovoltaic panels into alternating current, delivering it to the grid in three phases. These inverters are suitable for connecting two strings of panels and feature two maximum power point trackers, making them adaptable to different panel array configurations.
The primary function of these inverters is to facilitate grid-connected power generation from solar panels. They take the DC power from PV modules, convert it into AC power, and feed it into the utility grid. A complete PV grid-connected system typically includes PV modules, the inverter, an AC circuit breaker, an energy meter, and the utility grid. The inverter acts as the central component in this system.
The device also includes various protection mechanisms to ensure safe and reliable operation. These include DC reverse-polarity protection, a built-in DC switch, DC and AC surge protection (Type II), insulation resistance monitoring, and AC short-circuit protection. Grid monitoring and anti-islanding protection are standard features, along with a residual-current monitoring unit. For enhanced safety, string fuse protection and AFCI (Arc Fault Circuit Interrupter) protection are available as optional or standard features depending on the model.
Communication and monitoring capabilities are integral to the inverter's functionality. It provides two RS485 ports: one for monitoring one or more inverters and another for connecting to a smart meter, enabling an anti-backflow function. Additionally, the inverters support DRM (Demand Response Mode) communication. A USB-A port is available for connecting external monitoring modules like Shine WIFI-X, Shine 4GX, Shine LAN-X, or for firmware updates.
The inverter operates in several modes:
The Growatt MID TL3-X and MID TL3-XL inverters are designed for ease of installation and operation.
Maintenance is crucial for the longevity and optimal performance of the inverter.
