I gave this pump a 4 instead of 5 only because for the normal home owner wanting to install his/her own well pump the instructions are horrible or non existing! I would give this pump a solid 5 however because the quality, packaging, price was awesome! The shipping was pretty quick also. ..

Description

General Solar Off-Grid System Introduction 

The system is composed of solar panels, Solar Off-grid Inverter, MPPT charge controller and battery pack. Solar off-grid inverter is the core device
of solar power system, it converts DC power produced by solar panels to AC power to provide electric energy for appliances. MPPT charge controller
charges the solar electricity into batteries. When solar energy is not enough for the loads, or at night, the battery pack will discharge to replenish energy for loads.

System Features

     Safety

  • Overload and short circuit protection.
  • Auto restart while AC is recovering.
  • Compatible to mains voltage or generator power.

     Smart

  • Perfect pure sine wave output.
  • Selectable charging current.
  • Configurable AC/ DC input priority via LCD setting.

     Reliable

  • Built-in pure copper transformer.
  • Silicon-controlled rectifier(SCR) be adopted in AC by-pass.
  • Provide power supply to load for 24 hours.

    Intelligent

  • Advanced battery management system (BMS).
  • Support sealed battery and lithium battery.
  • Special AC output design, adopt emergency & heavy loads separate control.

How to Wire Solar Panel?

When solar panels are wired in a series, voltage is additive, but the amperage stays the same. But if you parallel wired panels the amperage would be additive, while the voltage remains the same.

5-star customer service. The pump I ordered was too wide to fit in a 4” well*. Armin and Chris were very helpful in communications by phone and email to return the pump and refund my money within a few days. I would have been happy to exchange for a different model but they didn’t have anything in stock that would fit. * the pump is 4" in outer diameter, with additional metal shielding on the side where the cord enters the case.

I live in the Bahamas and was greatly affected by Hurricane Dorian. Needed two pumps to help with our water problem. After 5 months it’s still not potable. I contacted Armin who was very knowledgeable and helpful. He even assisted me after purchasing the pumps with installation via Face time as I was not very familiar on what to do; and we have limited technicians here. He went above and beyond to assist me. Not many companies do that. I can definitely say this company cares about their customers. Thank you very much.

I gave this pump a 4 instead of 5 only because for the normal home owner wanting to install his/her own well pump the instructions are horrible or non existing! I would give this pump a solid 5 however because the quality, packaging, price was awesome! The shipping was pretty quick also. I wish I would have seen a spot to chat with an agent when I was trying to make the right selection although or a really good specs high light. Would be nice if you could at least put in information on what the well specs etc was and as a result of entering said information the computer kick back best choices. 👍 More information would be great and is needed. When it comes to your product it's well made and nicely priced! I am a small business owner so I do well pumps sometimes so I'm always looking for good quality for my customers and you guys definitely hit a high mark from us!
