Product Introduction
The EverPeak solar controller is the brain of a pressurized solar water-heating system. It reads collector and tank sensors and operates the pump only when there is useful heat to collect, protecting the system from nighttime reverse flow and overheating.
A clear LCD shows real-time temperatures, pump status and accumulated solar yield, while configurable timers and alarm outputs support frost protection, legionella prevention and backup-heater sequencing.
Models range from simple single-pump units to advanced controllers with multiple relays for drain-back, glycol and multi-tank setups.
Main Features
- Differential-temperature control with adjustable ΔT
- Large LCD with backlight
- Up to 4 sensor inputs (Pt1000)
- Relay outputs for pump and aux heater
- Frost, overheat and dry-run alarms
- Battery-backed memory
