The BEST new off-grid sump pump for dewatering without the grid! 

The most exciting sump pump system we have ever seen! Up to 90 GPM dewatering capability without grid power! Get max volume at lower heads with the GLS-90 model!

With the RPS Grid-less Sump Pump™ System you'll get reliable dewatering without the need for AC power or the utility grid. No more stress about flooding or water damage. A solar charged battery bank powers an ultra efficient permanent magnet driven sump pump to give you dewatering abilities if the grid goes down or you're off-grid, or don't have access to reliable AC power. 

RPS Grid-less Sump™ Pump brings a traditional-style sump pump off-grid, or gives you an all-in-one versatile super efficient dewatering pump system for agriculture that is not reliant on grid power or a generator. 

**** Hybrid+ Upgrade incorporates the Robust MPPT WS-3K Controller and batteries.
