Veichi SI30 Solar Pump Inverters — Weatherproof Outdoor Enclosures Rated IP65

The Veichi SI30 solar pump inverter series is engineered specifically for direct outdoor mounting in the most severe environments. The core distinguishing highlight is the heavy-duty cast aluminum alloy chassis with an IP65 protection rating, shielding internal electronics completely against heavy dust, field mud, and high-pressure water jets. This eliminates B2B panel layout design costs, allowing installers to mount the drive directly onto PV panel mounting racks in remote fields. The drive integrates advanced dedicated PV parameters: low PV voltage sleep mode (parameter F14.11, diagnostic code A.LPn) and sensorless dry run prevention (dry run current limit F14.17, code A.LuT) ensuring reliable operations.

Typical Applications for Veichi SI30

• Off-Grid Farmlands: Installed on metal support frames next to PV arrays directly in the open fields to drive crop sprinkler sets or automated drip loops.
• Pastures and Cattle Farms: Reliable water lifting for cattle watering troughs under aggressive outdoor conditions without building secondary structures.
• Remote Domestic Water Supply: Off-grid borehole pumping without risk of drive thermal trips inside closed distributions panels in hot summer climates.

What Differentiates Veichi SI30 from Competitors

Due to its cast aluminum frame, the Veichi SI30 provides vastly superior natural heat dissipation without relying on external cooling fans, which are prone to sand jamming and early B2B system failures.

When Veichi SI30 is NOT Suitable

• For massive agricultural pump complexes exceeding 11 kW motor capacity — select the high-power Veichi SI23 or the updated heavy-duty outdoor Veichi SI32 range.
• For indoor or cabinet distribution panel layouts where IP65 protection is redundant — the cost-effective Veichi SI21 series is highly recommended.

Our Engineering Integration Experience

The Veichi SI30 is our B2B team’s absolute favorite for off-grid Ukrainian pastures. It features a built-in reservoir overflow prevention system via dual-level sensor wiring (terminals X3 and X4, mapped to functions 80 — water full alert, and 81 — alert recovery), halting pump rotation with diagnostic code A.Ful. Built-in GPRS/Wi-Fi monitoring via the optional IOT-GWS module enables operators to view dynamic flow rates, output frequency, and reset faults remotely from any smartphone, saving long field trips.
