Guangxi, China / Rice Field Irrigation
SP4011 Solar Pump Cabinet for River Diversion Irrigation in Guangxi
Rice fields in Guangxi often need water at the right time, not only when grid power or diesel is convenient. In this project, water was diverted from a river about 180 meters away to support field irrigation.
The installed system used a SolarSeeker SP4011 control cabinet, an 11kW inverter, a 7.5kW pump, and 26 pieces of 550W solar panels. Stable water output was recorded around 3 PM, even with weak sun that day.
Model
SP4011
Inverter
380V / 11kW / 25A
Pump
7.5kW
PV array
26 x 550W
Water source
River, 180m away
Water Job
The river was close enough to use, but far enough to make pumping cost matter.
The project involved farmers moving from diesel power to a solar pump cabinet. For rice fields, irrigation timing is practical. If the pump cannot run when water is needed, the field suffers first and the electrical problem is discovered later.
River diversion
Water was drawn from a river about 180 meters from the field.
Weak afternoon sun
Stable water output was recorded around 3 PM when sunlight was not strong.
Simple start
The cabinet was built so the user could connect PV and pump, turn the switch, and run.
Cabinet Configuration
26 panels were wired as 13 in series and 2 strings in parallel
The installed setup used a 380V, 11kW, 25A SP4011 with three-phase output. It drove a 7.5kW pump for rice field irrigation.
The PV array used 26 pieces of 550W panels. With 13 panels in series and 2 parallel strings, the cabinet had a clear PV input plan and a simple operating surface for the user.
String design
13S x 2P
Application
Rice irrigation
Cabinet Lesson
A rice field system should be easy to start after delivery.
Before delivery
- Key controls arranged inside the cabinet.
- Breaker, indicator, and protection options selected for the project.
- PV string and pump output wiring planned before the cabinet reaches the field.
At the rice field
- The user connects PV and pump, then starts the system from the cabinet.
- Less generator work for routine river diversion irrigation.
- The same delivery idea can be repeated, but the pump and river distance still need checking.
Cabinet Selection Checklist
For rice fields, the cabinet choice starts with the pump and the water path
SP4011 matched this 7.5kW pump and a river source about 180 meters from the field. A different farm may need the same cabinet idea, but not the same wiring, inverter size, or panel string.
Need to confirm inverter range?
Start with pump voltage, phase, current, and motor power before choosing a cabinet.
Need a 380V three-phase system?
Use this path when the pump and PV array need a complete 380V layout.
Need pre-wired control and protection?
Use a cabinet when switches, breakers, indicators, and service access should be ready before delivery.
Need SolarSeeker to check the cabinet plan?
Send pump data, river distance, pipe route, panel model, and site photos.
FAQ
Questions from this Guangxi irrigation cabinet project
What configuration was used?
The installed system used a SolarSeeker SP4011, 380V / 11kW / 25A output, matched with a 7.5kW pump and 26 pieces of 550W solar panels.
How far was the water source?
Water was diverted from a river about 180 meters away.
Why use a cabinet instead of only an inverter?
A cabinet can combine the inverter, switching, breakers, indicators, and wiring in one controlled place, which reduces field setup work and makes daily operation simpler.
Can the same cabinet be used for another rice field?
Not without checking the pump nameplate, river distance, lift, pipe layout, desired flow, and panel model.
Need a pre-wired cabinet for farm irrigation?
Send pump data, water source distance, pipe layout, and panel plan. SolarSeeker can check cabinet size, inverter range, and protection needs.
