Installation Components & Schemes
Energy Meter (GMK110)
Brand: GOODWE
Model: GMK110
Manufacturer: GoodWe Technologies Co., Ltd.
Firmware Version: 00 03
Characteristics: 85~288 VAC; 120 A:40 mA; 5 Wmax; 50-60 Hz; 9600 imp/kWh; Power accuracy: 1%
Note: The GMK110 energy meter must be used in conjunction with the current sensor provided by the manufacturer for 1% total accuracy. An alternative power analyzer is admissible if it has the same connection regime, measurement tolerance, refresh time, and communication type.
Installation Schemes
Scheme for Single Inverter System
This scheme illustrates a single inverter installation. A PV string connects to a GoodWe Inverter. The inverter's DC output is linked to a GMK110 energy meter. The AC output from the inverter powers Loads and connects to the Grid. A Battery is also shown connected to the inverter.
Scheme for Multiple Inverters System
This scheme depicts a multi-inverter setup. Multiple PV strings feed into GoodWe Inverters (Master and Slave). Each inverter's DC output is connected to a GMK110 energy meter. The AC outputs of these inverters are connected to Loads and the Grid. A Battery is connected to the Master Inverter, and an "Ezlink" component is also shown.
Maximum Inverters in Parallel: Using the GMK110 energy meter, the maximum number of inverters connected in parallel is 8.
