KCP-5 Universal Solar Water Heater Controller

KCP-5 Universal Solar Water Heater Controller | Kaichang

Simplify solar thermal management with versatile water supply modes, seasonal operation, and clear temperature & level display. Designed for universal compatibility with non‑pressurized systems.

The KCP-5 is a universal solar controller designed for non‑pressurized solar water heaters. It offers flexible water supply options including automatic, timed, temperature‑triggered, and manual filling to accommodate various usage patterns. The unit displays current water temperature and level on a clear screen, with five level indicators for easy monitoring. Built‑in alarms notify users when water is low or the tank is full, helping prevent dry‑running or overflow.

For seasonal adaptation, this controller includes a winter/summer mode to optimize system performance across different ambient conditions. The U‑bend function accommodates specific piping layouts for easier installation. A manual drain‑back option allows users to empty the collector when needed. Temperature control is managed by a liquid expansion thermostat with a 0‑99°C range and constant‑temperature regulation.

This solar water heater controller can be paired with an anti‑freeze solar pipe valve for enhanced cold‑weather protection. For whole‑home convenience, integration with a whole house hot water recirculation system is supported to reduce wait times at fixtures. In hybrid configurations, a solar gas automatic switching sensor enables smooth transitions between energy sources. Kaichang manufactures this unit in Zhejiang, China, with a 250V, 10A power rating.
