Growatt MID 30000 TL3-XH 3-phase

The Growatt MID 30000 TL3-XH 3-phase is a 3-phase hybrid inverter that excels with good value for money.

The inverter has 3MPP trackers, to which 2 identical strings can be connected per tracker. So 3 orientations/slope angles can be used, which do not affect each other in case of shadowing, for example. Ideal if one part of the roof gets sun later than another. If you exceed the maximum of 1000 volts per string, you can choose to split the string into 2 identical strings, i.e. of equal length, equal orientation, equal inclination angle and approximately equal cable lengths, in order to split the voltage. So you can connect 6 strings of at least 200 volts to this Growatt inverter, of up to 60000 watt peak collectively. If the solar panels are producing at their maximum, and a battery is connected to the inverter, and the battery still has room to be charged, the inverter can supply a maximum of 30000 watts to the grid, and simultaneously supply 30000 watts to the battery. This is called Dual Power Function.

The inverter uses natural convection cooling, so no fans are needed and the system operates silently. Moreover, the Growatt MID 30000 TL3-XH is 3-phase transformerless, reducing energy losses and maximising efficiency.

The fact that the inverter is hybrid means that a home battery can be connected to it if required. The suitable battery for the Growatt MID 30000 TL3-XH 3-phase is the Growatt APX battery system for XH, with capacities ranging from 5 kWh to 60 kWh.

Note that you also need a Growatt Smart meter 3-phase to control the battery properly. You place this energy meter at the very beginning of your meter box, so that all incoming and outgoing energy of your entire house can be measured. You connect it with a data cable to the Growatt MID 30000 TL3-XH 3-phase hybrid inverter so it knows when to charge or discharge the battery. The energy meter also allows you to limit exports. This way, more inverter power can be connected to a grid connection without affecting the main fuse. The Growatt MID 30000 TL3-XH 3-phase cannot be used as a battery inverter. So with this inverter, you cannot choose not to connect solar panels, but you can connect a battery, and store the power from another brand of inverter in the battery.

If you also want to use the backup function, you also need the Growatt backup box for MID XH inverters. This EPS (Emergency Power Supply) function switches less quickly than the Growatt SPH series, so you will notice something in the event of a power failure. Because the inverter is transformerless, it is not recommended to connect any appliances with an electric motor to the emergency supply. Examples of such appliances are refrigerators, freezers, compressors, drills and washing machines. Still, it’s a nice idea that your lights and, for example, computer can work as usual when the power is out in the street. The standby consumption of this inverter is about 5.5 watts per hour.

Different priorities can be specified in the Growatt MIN XH inverters. Switching between these modes can be based on preset time schedules. So it is not a completely dynamic system based on power prices.

1. Load first: This mode ensures that produced solar power is sent to consumers in the home first. The excess power generated is used to charge the battery. When the battery is full, the remainder is fed back into the grid.
2. Battery first: With the solar power generated, the battery is charged first. If this is successful, the rest can be fed to the consumers in the house. If any power is left over, it is fed back into the grid.
3. Grid first: This setting ensures that all the power generated is fed directly into the grid.

Growatt has its own monitoring platform. If you want to use this, order a monitoring module with it. Using a Wifi-X, LAN-X or Shinelink-X dongle, you can establish a connection between the inverter and the internet, allowing you to remotely view the performance of your solar panels on your computer, tablet or phone. No connection for a while? No problem at all. The dongle has a large memory, and as soon as the module can connect again, all the information is neatly transmitted and converted into a graph.

Growatt offers a standard 5-year warranty on this Growatt MID 30000 TL3-XH 3-phase inverter!
