HSPH2200L

HSPH2200L is a solar pumping inverter for a 2.2 kW monofásico / trifásico AC pump: not a pump and not a panel, but the drive that stands between the two. The array’s DC comes in, the drive holds the array at its maximum power point, and what leaves it for the pump is AC at the voltage and the frequency the motor was built for. The frequency follows the array rather than a fixed supply, so the pump turns at the speed the sun can pay for at that moment, and the day’s water is pumped while the sun is up. This model also states an AC input: grid or generator is switched in while solar is low, and switched out again as solar recovers. Nothing is stored in a battery: the energy is stored as water in a tank or a reservoir.

An existing 2.2 kW AC pump does not have to be replaced to run on solar. It needs the right drive in front of it, and HSPH2200L is that drive: the motor, the pipework and the wiring stay where they are.

For this model the datasheet states an array window of 200V minimum Vmp and 450V maximum Voc, 11A of rated input current over one string, MPPT at up to 99%, an output of 220/240 V at 50-60 Hz, an IP65 enclosure for mounting on a wall outdoors, a water level input for a well or a tank and an optional 4G/Wi-Fi module for remote monitoring.

What that buys is a pumping day with no meter running: the fuel bill or the grid bill that used to arrive with every hour of pumping goes, and the pump that was already paid for keeps working. The protections are built in rather than added — Solar DC input Low/Over Voltage, Solar DC input Reverse Polarity, Over Flow of Tank, Against Lightning, AC input / Output Phase Lost, Dry-Run (detecting by Sensor or Software), AC Output Short-circuit, AC Output Over Current, Over Temperature, Over Load — so a dry well, a low array or a hot afternoon costs a shutdown rather than a motor. The array is not guessed either: the array window is what the string has to sit inside, and the sizing is read from the pump’s duty point rather than from a rule of thumb.

To confirm this model against your pump, send the nameplate details — power, voltage, phase and rated current — and we check them against this model’s own figures before anything is ordered. The code to quote is HSPH2200L.
