today i want to tell you about our gridless sump pump systems this is mike with rps solar
pumps here and this pump here in this system is based upon our tankless pressure pump system that
provides constant pressure to your household or other off-grid needs where you need to produce
pressurized water we've taken that system and redesigned it into a submersible sump pump
we have two different models of these sump pumps one is the gls 90 and the other is the gls 30.
depending on the amount of water you need a pump per minute or the pumping head you'll
select either of the two models the gls 90 will do around 90 gallons per minute
but it has a maximum pumping head of around 5 feet and you don't want to go past 7 to 10 feet
that's where it starts topping out and the water drops off and you won't be producing as much our
other model the gls 30 will do around 30 gallons per minute and this one is ideal for around 50
feet of pumping head and it starts to top out at around 100 feet of pumping head so really you want
to stop at 50 but you can push it up to 60 70 or 80 feet but you're going to start losing some of
that gallons per minute this system is great for all your dewatering needs whether you're pumping
clean or dirty water it's not going to matter that includes some pits pumping out of rivers and
streams pumping out of trenches or canals anywhere you need to move a large amount of water on demand
they feature a brushless dc motor with permanent magnets those are the most efficient making sure
you're pumping the most amount of gallons per watt of solar hitting your panels depending on which
pump you get you're either going to get a two inch outlet with the gls 90. it has the barb fitting
plus not shown here there's a two inch female npt pipe thread whether you want to do flexible
pipe or whether you want to connect to pvc or a different type of metal pipe on the gls
30 it's a one inch outlet it has both a male npt fitting and also a barb down below
whether you want to do flexible pipe here or if you want to do pvc connection the inlet of both of
these is stainless steel and the bottom features a screen so it'll help filter out any particles
that are too big for this pump to handle the body is aluminum and the base is cast iron here
it's built for years of service what we've been able to do is we shrunk down our circuitry to fit
in the top of the motor here and it features soft start so it ramps this pump up and down
it drives the permanent magnet motor so it's going to be the most efficient
operating motor possible and it also has low water detection so that means if you start sucking air
because you pumped your location dry it's going to shut off the motor for 15 seconds wait for the
water to rise back up and then start pumping again what that's not is it's not a low water shut off
meaning it's not a float valve if you do need de-watering applications where once you've
drained it out and it's not getting more water in there and you need the pump to shut off for long
periods of time you're going to need to add on a float valve in order to cut power the pump until
that water level rises back up over the top but as is we have a constant stream of water coming in
this is a perfect application the kit comes with everything you see here and it's one of the only
solar powered sump pumps on the market today over here we have our pumps i've explained those and
here's the brain of the system the controller what this does is it takes power from our solar panels
and it charges up our batteries and then when the pump needs power it sends power to the pump
and allows it to pump the water batteries are optional but we do recommend getting them from
us when you get them from us it's sized so you have the right number of panels and you have the
right number of batteries whether that's 4 6 8 12 batteries depending on your water pumping needs
these are deep cycle 12 volt vlra gel batteries these are some of the highest quality on the
market and made for extreme environments and deep cycles which you'll need in order to pump another
great thing about this controller is it has 220 volt ac input that means if you have a week of
cloudy days and your batteries depleted you're able to recharge your batteries or load transfer
and run your pump directly off of the 220 volt source whether you plug it into utility power
or use a generator in order to recharge your battery but normally you won't have to use that
you'll have plenty of solar on sunny days in order to recharge your system and you won't have
to depend on the ac input unless you're doing a lot of pumping or like i said you have a lot of
cloudy days in a row the system is based on the technology we developed for the tankless pressure
pump system which we've had great success with over the last year we've taken that technology
and now put it into a sump pump system in order to provide backup power for your dewatering needs
whether it's a storm knocks out your power and you need to keep the water out of your basement or
you need a pump from a trench and fill up a trough for a livestock this system will do it all for you
if you're interested in one of these systems give us a call at 888-637-4493 or visit us at
we have people standing by who can help you size a system and make sure
this is going to be a perfect fit for your dewatering needs
