3-Year Warranty Solar Water Pump 48V Deep Well
The 3-Year Warranty Solar Water Pump operates at 0.7HP with 48V DC, supporting up to 390 feet of head and a flow rate around 9 GPM. It features a 3/4” stainless steel deep-well submersible design suitable for boreholes, with durable construction for both residential and industrial use. The system supports battery backup to enable on-demand pumping, and is intended to be connected to a solar panel (not included). Water shortage sensors automate shut-off when the header tank is full or the intake depth falls below the pump.
3-Year Warranty Solar Water Pump Kit – 24V Deep Well
This kit uses a 0.3HP, 24V DC deep-well submersible pump rated for up to 260 feet of head and approximately 7.7 GPM. Built from stainless steel, it is suitable for home and industrial use, and supports battery-backed operation for on-demand pumping. It is designed to connect with a solar panel (not included) to maximize energy conversion while remaining environmentally friendly. Automated operation relies on water shortage sensors to stop pumping when conditions change.
Solar Water Pump Kit 24V With MPPT Controller
The 24V Solar Water Pump Kit features a 0.4HP stainless steel submersible pump capable of up to 320 feet of head and around 7.7 GPM. It includes an MPPT controller to optimize energy harvest from solar panels, reducing overall energy costs. Like other models, it supports battery backup for pumping on demand and employs water shortage sensors to automatically shut down if the water source is depleted or the header tank is full.
12VDC Solar Hot Water Pumps
These 12V DC solar hot water pumps handle temperatures up to 230F and pressures up to 145 PSI, with a three-phase ECM brushless DC motor. Certified with FDA and CE marks, the system operates from 6–24V and offers a max flow around 12 L/min. It demonstrates robust performance for pond and small borehole applications with a focus on high-temperature tolerance and reliability for continuous operation.
US SOLAR PUMPS.COM offers 12V DC solutions suitable for deep water applications with a maximum head of about 3 meters and a flow rate of approximately 12 L/min. The model emphasizes a durable build, suitable for long-running operation, and is designed to work with solar power arrays. The system aligns with food-grade materials and aims to provide steady, off-grid water supply for residential settings.
Buying Guide
- Voltage and compatibility: Choose pumps that match your solar array output and battery setup. Higher voltage systems (24V, 48V) generally handle deeper wells and higher heads more efficiently.
- Head and flow requirements: Determine the vertical lift (head) and desired flow rate (GPM or L/min) for your borehole or pond. Match the pump’s specs to your water needs and well depth.
- Materials and durability: Stainless steel 316/304 constructions resist corrosion in well water. Look for submersible designs rated for long-term underground use.
- Control and automation: MPPT controllers, solar panel pairing guidance, and water shortage sensors help optimize energy use and prevent dry-run damage.
- Backup power and reliability: Systems that accept battery backup or hybrid operation provide flexibility for cloudy days or nighttime pumping.
- Installation and maintenance: Consider pump size, ease of servicing, and compatibility with existing solar panels, wiring, and headers.
- Safety and certifications: Check for certifications (FDA, CE, RoHS) and safety features such as automatic shut-off when water is depleted or tanks are full.
- Warranty and support: A 3-year or longer warranty and solid customer support help address potential issues with deep-well usage.
- Price vs. long-term value: While initial costs vary, prioritize total cost of ownership, including efficiency, durability, and potential energy savings over time.
When selecting a solar pump for deep wells, consider your well depth, desired flow, climate, and whether you want to integrate with a monitoring system. The options above are designed to deliver reliable performance while minimizing grid dependence, leveraging solar power for consistent water access in rural or off-grid settings.
