Veichi SI23: when this series fits a deep well, and when SI30 is enough
We stock Veichi SI23 for one customer profile: large agricultural wells and municipal water supply where the pump runs three-phase from 37 kW upwards. A typical scenario this year: a farm in Kherson region installs an SI23-T3-075G-A (75 kW, 150 A) on a 120 m well for drip irrigation of 80 ha, paired with a 90 kW solar array. The inverter is hybrid: it pulls from solar during the day, then tops up from the 380 V grid in the evening. If you have a residential pump up to 11 kW, SI23 is not for you, take SI30.
Top three models from our stock. SI23-T3-037G-A (37 kW, 75 A): for 60-80 m wells under drip irrigation across 30-50 ha. SI23-T3-075G-A (75 kW): municipal stations supplying a village of 500-1500 residents. SI23-T3-110G-A (110 kW, 210 A): for deep artesian wells 150-200 m in industrial water supply.
What we ask before the SI23 order: pump, panels, scheme
One: actual pump power from the manufacturer datasheet, not the nameplate (nameplates often overstate it). We pick the inverter with a 15-20% margin, because the inrush current of a submersible pump runs 4-6x rated. Two: what solar array you plan and what MPPT input voltage (SI23 handles 250-800 V on the DC input). Three: is there a 380 V grid, and will you run Net Metering. If the grid is stable, the inverter balances on its own. If there is no grid at all, you need a battery buffer with storage or daytime-only operation.
We are an authorized Veichi dealer since 2014; we keep the full SI23 line from 37 to 200 kW, plus motor cables and flanges. Manufacturer warranty 24 months, delivery from our Kyiv warehouse: up to 75 kW in 1-3 days, from 110 kW by truck in 5-10 days. For full-scope projects (solar array + pump + controller) we run the scheme calculation for free. Accessories and complete kits in the solar pump inverters section.
