SolarRO SW 18

Solar-Powered Brackish Water Reverse Osmosis System

The SolarRO BW30 provides clean, safe water from seawater and high-salinity water sources using renewable solar energy. Equipped with the patented adaptive ANVS®* mechanical valve. The system automatically balances reverse-osmosis pressure when sunlight or voltage fluctuates — ensuring continuous operation even under direct solar or weak unstable grid power. Operate the unit on solar only, grid only, or blending both for hybrid operation. By maximizing solar input, it reduces energy costs and carbon emissions — delivering sustainable, low-cost water wherever it’s needed.

Fast to Deploy. Easy to Operate.
The pre-assembled plug-and-play system guarantees fast installation with minimal commissioning effort. No on-site adjustments or continuous operator presence needed. With remote monitoring, self-regulating pressure, and low maintenance needs, the system delivers predictable and efficient performance, with fewer service visits.

Built to Last.
High-quality, corrosion-resistant components ensure long life in remote, off-grid, and demanding environments. Industry-standard components allow easy servicing and global availability of consumables and spare parts. The robust design maximizes reliability and extends the system’s operational life.

Trusted, Clean, Safe Water.
Treats lake, river or brackish borehole water. Removes sediments, salts, bacteria, and viruses, producing drinking-quality water that meets global safety standards.
