connected to this equipment, a photovoltaic panel will charge the DC link capacitors. D. Energy stored in this equipment’s DC link capacitors presents a risk of electric shock. Even after the unit is disconnected from the grid and photovoltaic panels, high voltages may still exist inside the PV-Inverter. -
Page 7: Connecting To The Grid (Ac Utility)
A. Measure grid (utility) voltage and frequency. It should be 230VAC (or 220VAC) , 50/60Hz and single phase. B. Open the breaker or fuse between PV Inverter and utility. C. For Inverter (CMS 4000 and CMS 5000 ), connect AC wires as follows: Edition 2.0 2010/06... -

Current) power. Because Inverter is grid-connected it controls the current amplitude according to the PV Panel power supply. Inverter always tries to convert the maximum power from your PV panel(s). C. Connection system: This “interface” between Utility and PV-Inverter may consist of electrical breaker, fuse and connecting terminals. - Page 11 information: Automatic ON-OFF: Inverter starts up automatically when DC-power from the PV panel is sufficient. Once the PV-Inverter starts it enters one of the following 3 states: Standby: The PV string can only provide just enough voltage to minimum requirements of the controller.
