victron energy BLUE POWER SOLAR SWITCH

VE SolarSwitch No-break back-up for grid connected solar systems Introduction: preventing shut down of the PV system in the event of a power outage A rapidly growing number of houses, farms and other buildings are being fitted with grid connected solar installations. The standard configuration has an important drawback: it is dependent on the grid. If the grid fails, the grid connected inverter shuts down and a total blackout is the result, despite the investment in a solar installation. The same is true for other grid connected alternative energy solutions, such as wind, water or micro CHP...

The solution a Victron MultiPlus or Quattro inverter/charger with SolarSwitch Figure 3: Two meter system with MultiPlus and SolarSwitch When the public grid is available, the Victron SolarSwitch will connect the solar inverter directly to the grid. If the grid fails, the power from the solar inverter will be redirected to the output of the MultiPlus. The MultiPlus replaces the grid and will balance the power mismatch between the load and the solar inverter. A power shortage will be supplemented by the MultiPlus, discharging the battery, and excess power will be used to recharge the battery....

Operating modes oF an on-grid system with SolarSwitch • A. The grid is present All loads are supplied by power from the grid. Solar power is directed to the grid. • B. Grid failure The water heater is disconnected. Solar energy is used to supply the protected loads and/or to recharge the batteries. • C. Batteries discharged All loads are disconnected. Solar energy is used to recharge the battery. The loads will be reconnected after (partial) recharge of the batteries.

Important features After installation, the MultiPlus or Quattro is ready for use. If settings have to be changed, this can be done in a matter of minutes with a new DIP switch setting procedure. Even parallel and 3-phase operation can be programmed with DIP switches: no computer needed! Alternatively, a VE.Net or Blue Power panel can be used instead of the DIP switches. Sophisticated software (VE.Bus Quick Configure and VE.Bus System Configurator) is available to configure several new, advanced, features. Integrated Battery Monitor At request all Multi’s and Quattro’s can be fitted with an...
