I have a solar heating panels on a 2 story home, Can variable speed pump deal with this?

Absolutly, this pump can really move some water at 3 and 4 of the variable speeds. you should have no problem at all with this pump getting water to the panels.

I have two large solar panels that are temperature controlled. As soon as the temperature rises and the valve opens to the solar panels, the pump increases speed until the panels are filled (they empty at night in case of frost). As soon as the panels are filled the pump slows to the required galls/min. However note that the power required - that is the Watt draw will be higher since it has more work to do lifting the water to your roof. The short answer is - it works great. It is a really good pump.

This would not be a problem for the pump, but you would need a controller panel for it where you could schedule any change in speed and simultaneously control any valves that might need to be opened or closed. I would call their technical customer service. My phone call to them after a long wait was more helpful than I anticipated.

I would venture that the answer is "yes." The pump is both powerful and intelligent; it's easily capable of exceeding the pressure rating of my DE filter (80 psi). As always, check with the manufacturer but if you can determine what the range of flow rates are for your solar assembly (min/max gpm) you can then easily program the pump to maintain those flow rates.

no the pump will stop working. get a solar pressure pump there about 125.00 to operate the water tank.

yes-I manage my water heater for time of use and it works perfect.The only thing you might want to check if your amperage draw isreal high . I doubt your pump motor is over 5 HP so it would be it would be more than adequate.

As long as your pump runs on 110 volts and does not pull more than 10 amps, (1/2 HP or less).

Solar panel on my fence. Otherwise the pump totally submerge and needs to be

I've run the pump for 6-8hrs at a time to heat a kiddy pool with an electric heater, so you should be good as long as you have the flow of water all able to move through your solar panels. If the flow through the panels restricts the flow from the pump you will then have the pump turning off and on from the pressure switch on the pump. Running the pump for such longer durations mainly affects the longevity of the pump, but I sacrificed that for having happy kids playing in a warm kiddie pool.

Not sure, I bought this for my boat. It draws I think 2 to 3 amps so you will need to make sure that your solar panels can supply at least the amount of amps the pump draws and is 12 bolts.

It is an excellent machine even though it is loud. As the labeling suggests, it will handle up to 15,626 watts. So you should check your heat pump and see what it requires. It runs our air conditioner (whole house) fine, but we have not run an heat pump.

Yes, but we easily swapped out the electric pump for a solar pump and it works great.

I am a HVAC contractor and have used at least a 100 of these styles. The contacts at 240v can handle .5 amps- if your load is close to that and you want to extend the life of the control you can use the ETC to switch a pilot duty relay and let the relay control the pump.

No. The function of your solar heating pump is a steady, low flow and if your solar panel is on a roof, say a lift of 10' to 15', the pump must be rated to that height. Sump pumps are designed to have a high flow rate for short duration, just the opposite of what you will need.

I haven't tried what you're asking but don't see why not if you can find a 24 volt relay that can handle the pump's voltage and amperage (wattage).

Assuming there is a constant 12 volt direct source, the pump is going to draw 3 to 5 amps. amps x volts = watts. At 5 amps that would be 60 watts. With a battery in line it would work. Straight off a 50 watt solar panel probably not so well.

I don't believe it will work... specifically with the minimum one battery set up. It may work with several batteries but suggest you contact Grape Solar directly for assistance. They have been very helpful with my questions over the phone, (1.541.349.9000). I have operated smaller pumps for brief period but not 1.5hp. I believe you are also going to be using a lot more than the 400 watt output of the 4 panels... you may need to be generating closer to 1500 watts to continuously run the pump.

Yes, the variable speed wires in to the same 240 volt power just like your single speed pump. The EcoStar has more control options that can be utilized at your control box. I am using an older Jandy box as my main control unit and just using the onboard controls on the EcoStar to program time and speed settings.

I've had no issues with it working. Again as stated by the others the solar panel has to be in direct sunlight. Make sure the pump has been connected properly & it should work.

I have 4 of these pumps driving 4 separate zones in home. All 4 are attached to an Argo ARM-4P (http://www.amazon.com/Argo-Control-Switching-Relay-ARM-4P/dp/B00DNGCAHY) which takes the (low voltage) input from 4 thermostats and flips on the appropriate 115 volts to drive the Grundfos pump. I use the speed settings on each pump to set how fast I'd like that zone to heat up when its thermostat calls for hot water. The pumps that control the main part of the house are set to "3" (high), and in the less used portion of the house are set to "2" (medium).
