Page 11: Design Guidelines
PRO208V-5k75 Installation and Safety Manual Design Guidelines DC Stacking Ratio 5.1. The ratio of PV module STC power rating to inverter output power rating is often referred to as “Stacking Ratio.” Most PV installations are designed for a stacking ratio greater than 1, and less than 1.5. However, the only real limitation on stacking ratio for the inverter is the voltage and current limitations of the string inputs. -
Page 12: Inverter Placement
PRO208V-5k75 Installation and Safety Manual Inverter Placement The ProHarvest 208V inverter is NEMA6 rated and may be placed almost anywhere. Cooling is most efficient if the unit is mounted vertically in the shade, bolted to racking and with the connectors pointing downwards. However, any orientation is acceptable. -
Page 13: Grounding
PRO208V-5k75 Installation and Safety Manual Grounding The metal enclosure of the inverter must be grounded according to NEC 690.43. Equipment ground is provided through the AC connection.

Page 15: Connection Outline
PRO208V-5k75 Installation and Safety Manual Connection Outline 6.2. Connection occurs in the following order: 1. Connect an equipment ground to the inverter. This should always be done first. 2. Connect the inverter to the grid. 3. Connect the Communications Gateway to the same 208 Vac circuit as the inverter and the network. 4. - Page 16 PRO208V-5k75 Installation and Safety Manual (b) Mate the male and female AC Connection connector to connect the inverter to the AC system. Use the AC tool to disconnect the male and female connectors. Follow steps 1 through 3 in the Disconnection section of Figure 11.
- Page 17 PRO208V-5k75 Installation and Safety Manual (b) Connect power to the Gateway using the appropriate AC cable (Figure 13). Ethernet may also be connected at this stage. Figure 13: Making Gateway connections AC Connection Ethernet Connection (optional) (c) Turn on power to the inverter. On the Gateway screen, select the Inverters tab A at the top of the screen if the unit is not already on that tab.
- Page 18 PRO208V-5k75 Installation and Safety Manual 5. Turn on the AC source. This starts a 5-minute timer. When it expires, each inverter will perform a self-test and then begin generating. During the wait period, the inverter button will be solid green. (See Table 2 on page 20.) This does not apply if the system is in the Off + Locked state.
