Increasing capacityfor SOLAR WATERSOLUTIONS with RSIThe intelligent IP66 off-grid Solar Inverter (RSI) is designed torun with large Grundfos pumps, greatly expanding possibilitiesfor solar water solutions offering low (or nearly no) operatingcosts.

The RSI is incredibly easy to setup and install, and pairs

easily with SP submersible pumps as well as a broad range ofGrundfos pumps, creating a modular system which allowsmaximum components exibility.

AN INVESTMENT THAT PAYS FOR ITSELFTHERE ARE SUBSTANTIAL BENEFITS OVER TIME WHEN INSTALLING A SOLAR WATER SOLUTION,PAYBACK TIME IS OFTEN SURPRISINGLY QUICK.

If you already have an SP pump installed and can see just how high your energy and perhaps fueltransport costs really are, then you should consider a solar energy solution using a solar inverter. WithGrundfos, retrotting a solar energy source to your SP pump is straightforward and the cost benet isimmediate.

Weatherproof for outdoor installationWith an IP66 enclosure class rating, the RSI is resistant to rain, dust andsand, meaning there is no requirement for a weatherproof cabinet withventilation and air lter. The RSI can handle ambient temperatures up to60 C. In addition to substantial cost savings for installation, placing thesolar inverter beneath the solar panel array means only a very short DCcable is required, and this is an extremely important safety advantage

for users and personnel.

Continuous system optimisationAdvanced MPPT software continuously optimises the system by com-pensating for environmental effects on solar panel array, improvingpower and water output by up to 30 %. Environmental effects cover

1) temperature compensation,2) handling of multiple local power points due to partial shading, and3) protection against power oscillation due to rapid cloud

movement.

Quick setup with Grundfos pump motorsThe quick setup Wizard pairs the RSI quickly with a broad range ofGrundfos pumps. With a built-in Grundfos motor library all that isrequired is conrmation of motor type and pre-set value; no parameterinput is necessary for Grundfos pumps. This means

1) setup completed in less than 5 minutes, and2) enables setup of the RSI in the workshop prior to a plug-and-

pump experience on site.

AC/DC compatibleYou can switch the solar inverter to mains power or generator ifrequired, because the drive is compatible to both AC and DC powerinput without the need to change any parameter settings. Simplyconnect the two power sources via an external switchover box, and you take advantage of solar energy during the day and mains power orgenerator during the night.

The RSI is designed to work with a broad range of submersible andsurface pumps. A solar energy water supply system with a solarinverter can run a Grundfos pump up to 37 kW in size.

The RSI is available in two models:

Correct sizing of your solar energy water supply system Getting pump sizing right is important and should always start withthe specic application and a focus on the entire system. Taking intoconsideration the seasonal, climatic and geographical uctuationsin the availability of solar energy is also necessary.

For this reason, you need to talk to Grundfos to ensure correct sizingof your solar energy water supply system and use our sizing toolavailable on Grundfos Product Center.
