NASTEC SUND 50 – Solar Swimming Pool Pump
Design, Engineering & Assembly 100% in Italy 🇮🇹
Suitable for pools up to 520 m³, the SUND 50 can be used as a single unit or scaled up using the unique COMBO mode, connecting up to 8 pumps in cascade for large pools and commercial installations.
★ COMBO Mode – Scale Up to 8 Pumps
To maximize efficiency and reliability for large pools, instead of using a single high-power pump, the SUND system allows you to split the load into two or more pumps in parallel, each controlled by its own variable speed inverter and powered by the same PV system.
- Up to 8 SUND pumps can be connected in COMBO mode via RS485
- One inverter acts as master (address 00), others as slaves (addresses 01–07)
- Cascade operating principle: pumps start and stop automatically based on available solar power
- In low irradiance conditions, at least one pump continues to operate — ensuring continuous water circulation even on cloudy days
- Ideal for pools from 60 m³ up to 480+ m³
Pool Sizing Guide – SUND 50
Use the table below to determine how many SUND 50 pumps you need based on your pool volume:
