Hainan, China / Fish Fry Pond Aeration / SP4015
SP4015 Solar Inverter for an 11kW Fish Pond Oxygen Generator in Hainan
A fish fry pond cannot treat aeration as an optional daytime load. The oxygen generator needed power through the day and night, because interrupted aeration can put the pond at risk quickly.
The Hainan system used a SolarSeeker SP4015 inverter rated 380V / 15kW / 32A, an 11kW aerator load, and 26 pieces of 550W solar panels arranged as 13 in series and 2 parallel strings. Solar power handled daytime operation, while grid power supported the night load.

Load Requirement
The oxygen generator needed a 24-hour power route.
For fish fry farming, aeration is a production load. Solar can reduce daytime grid use, but the system still needs a stable plan for night operation and weak-sun hours.
The SP4015 was used as a hybrid power control point: PV power during the day, grid support at night, and controlled motor output for the aerator load.
Operating Logic
Solar first, grid support, and fewer aerators when sunlight is weak.
Daytime PV operation
The inverter uses solar power when available, reducing the grid energy needed for pond aeration during sunlight hours.
Night grid support
The pond still needs oxygen after sunset, so grid power keeps the load supplied when PV input is not available.
Load reduction under weak sun
When solar power is limited, the system can reduce the number of aerator pumps under control instead of forcing the full load onto weak PV input.
Special Motor Load
One inverter path had to manage more than a single pump start.
Project control needs
- AC and DC hybrid power input.
- Remote control by mobile phone.
- One inverter controlling six aerator pumps in the selected system route.
Why this matters
Aerators are motor loads, but the pond owner cares about oxygen supply. SolarSeeker has applied this inverter control route to more than 200 aerators, with operating records over two years in this application group.
For Fish Pond Owners And Installers
Treat the aerator as a motor system, not only a solar panel count.
Before quoting, SolarSeeker needs the aerator motor data, number of pumps, running schedule, power source plan, and whether remote control is required.
Check the inverter family first
Use pump or motor voltage, phase, current, and running schedule.
Use SP4 for 380V three-phase loads
SP4015 belongs to the SP4 380V project path.
Need controller selection help?
Useful when the load is an aerator, oxygen generator, or other motor system.
Need a 24-hour aeration plan?
Send aerator nameplate, pump count, PV module data, grid condition, and pond running schedule.
FAQ
Questions from the Hainan oxygen generator project
What configuration was used in Hainan?
The system used a SolarSeeker SP4015 inverter, 380V / 15kW / 32A output, an 11kW aerator load, and 26 pieces of 550W panels arranged as 13S x 2P.
Why did the system need grid support?
The fish pond needed aeration at night as well as during the day, so PV power alone was not enough for the full operating schedule.
Can one inverter control multiple aerator pumps?
For this application route, SolarSeeker designed control for six aerator pumps through one inverter system. The final design still depends on the motor data and site wiring.
What data should a fish pond owner send?
Send each aerator motor nameplate, pump count, running hours, PV module model, grid condition, and whether remote control is needed.
Planning solar power for fish pond aerators?
Send the motor nameplates, pump count, operating hours, PV panel model, and grid condition. SolarSeeker can check the SP4015 route before quotation.
