Installation and operation guide for the Blue Sky Energy 1524iX MPPT solar charge controller, covering safety, wiring, settings and troubleshooting.
The Blue Sky Energy 1524iX is a 12 V or 24 V multi‑stage MPPT photovoltaic charge controller that delivers up to 15 A (24 V) or 20 A (12 V). This manual provides important safety instructions, product description, wiring diagrams, configuration settings, and troubleshooting steps for proper installation and reliable operation.
Key features include three‑stage charging (Bulk, Acceptance, Float), optional temperature compensation, IPN network support for up to eight controllers, and protective functions such as over‑voltage, reverse polarity and over‑current limits. Follow the safety guidelines and wiring recommendations to ensure a safe, code‑compliant installation.
| Maximum charge current | 15 A (24 V) / 20 A (12 V) |
|---|---|
| Supported battery voltage | 12 V or 24 V |
| Maximum charge voltage setpoint | 15.5 V (12 V) / 31.0 V (24 V) |
| Temperature compensation factor | -5.00 mV/°C per cell |
The controller uses Bulk, Acceptance, and Float stages: Bulk delivers maximum current until the acceptance voltage is reached, Acceptance holds the voltage to finish charging, and Float maintains a lower voltage to keep the battery fully charged.
Yes, up to eight controllers can be connected via the IPN network to operate as a single charging system, sharing a display and temperature sensor.
