The new LCD PowerStation Webserver and Local LCD display
SAVE 30% When purchased with a REC BMS!
The S3 and P4 share the same bezels, screens, and cloud platform — but they're aimed at very different installations. The S3 is a focused, value-priced panel for a single REC BMS. The P4 is the flagship: faster silicon, broader I/O, and a feature roadmap that grows with the DC Powerworld ecosystem.
