The SN2200 is a 2.2-kilowatt hybrid inverter specifically engineered for three-phase submersible or surface water pumps. Its core purpose is to convert DC electricity generated by solar photovoltaic (PV) panels into AC electricity with a stable voltage and frequency suitable for standard induction motors. Unlike conventional solar pump inverters that only operate when the sun is shining, the hybrid capability permits simultaneous or priority-based use of solar and AC grid power. This ensures uninterrupted pumping even during night time or heavily overcast conditions, making it a valuable tool for remote and off-grid communities.
The input voltage range is a critical parameter. Common DC input levels include 12V, 24V, 48V, 120V, 220V, 360V, and 480V. The 220VDC rating is particularly notable because it aligns with a nominal PV array voltage that many modules achieve in series connection. For instance, a PV string composed of 10 to 11 typical 24V modules (open-circuit voltage around 45V each) or 6 to 7 high-voltage modules can produce a nominal DC bus around 220–250V, making the inverter highly adaptabl
The power rating of 220VDC inverters typically ranges from 0.37 kW to 7.5 kW, although larger units up to 15 kW exist. This makes them suitable for pumping depths of 10 to 150 meters and flow rates of up to 80 m³/h, depending on the pump’s hydraulic curv
Solar inverter pumps represent a mature, practical technology that addresses two pressing global challenges: sustainable energy and water security. Their ability to convert variable solar power into efficient pumping makes them superior to conventional diesel or fixed-speed electric pumps in many off-grid and grid-connected applications. While initial costs and technical hurdles remain, the long-term economic, environmental, and social benefits are substantial. With continued innovation and supportive policies, solar inverter pumps are poised to become a backbone of modern sustainable agriculture and rural water supply systems worldwid
While exact specifications may vary by manufacturer and revision, the SN2200 is generally characterized by the following representative values: rated output power of 2.2 kW, three-phase output at 380 V and 50/60 Hz, and DC input voltage range of 120 to 400 V. The maximum PV input power is often around 3 kW, allowing a generous PV-to-pump power ratio to compensate for cloudy conditions. The inverter's efficiency in grid mode is approximately 95%, while MPPT efficiency is around 99%. The operating ambient temperature range is typically -10°C to 50°C, and the unit weighs about 8-10 kg, with dimensions around 300×200×120 mm. These specifications make it suitable for pumps with a head up to 120 meters and flow rates varying from 5 to 30 cubic meters per hour, depending on system design.
Installation and Maintenance
Installation of the A-series is straightforward. The DC input from the PV array is connected to the designated positive and negative terminals, while the AC output is wired to the pump motor. A grounding terminal ensures safety. The unit must be mounted vertically on a clean, shaded surface to allow proper cooling. Many models come with a built-in cooling fan, but adequate clearance around the heat sink is recommended. Routine maintenance is minimal: periodic inspection of wiring connections, cleaning of dust from the heat sink, and verifying that the cooling fan operates correctly. Because there are no brush contacts or moving parts inside the inverter itself, the expected lifetime exceeds 10 years under normal us
A critical feature is the ability to use a three-phase pump even with a DC power source. This eliminates the need for expensive DC submersible pumps, which often have lower efficiency and higher maintenance costs. The 220VDC input is particularly efficient because higher DC voltages reduce current for the same power, allowing thinner copper cables and fewer resistive losses compared to lower voltage system

Solar water pumping systems have emerged as a sustainable and cost-effective solution for irrigation, rural water supply, and livestock management, particularly in off-grid and remote areas. At the heart of these systems lies the solar pump inverter, a power electronic device that converts variable direct current (DC) output from photovoltaic (PV) panels into a stable alternating current (AC) supply suitable for driving standard AC water pumps. Among the various DC input configurations, the 220VDC solar pump inverter has gained significant traction due to its optimal balance between system voltage, cable sizing, If you adored this article and you also would like to be given more info relating to newpro Voltage stabilizer please visit our web-site. and compatibility with common PV array layouts.
