Product Description

SR501 1500W Solar Controllers for Compact Non Pressurized Solar Water Heater

1. Produuct Introduction

1.1 Overview

SR501 microcomputer automatic controller is used for intelligent control of Integrated non-pressure solar water heater. It is developed with the latest NEC high-performance single-chip microcomputer and realizes intelligent control. All devices adopt industrial grade standard and can operate freely in cold, high temperature and humid environment. At the same time, the clock chip is used to make the time control accurate. The controller LCD liquid crystal display, beautiful appearance, stable and reliable performance, easy installation, is the most ideal accessory product for  Integrated non-pressure solar water heaters.

1.2 Function
