Solar Charge Indicator

A simple diagnostic tool that confirms at a glance whether your solar panel is actively delivering current to the battery. An integrated LED illuminates when charging current is flowing and stays off at night or in low light. Compatible with 12V and 24V systems up to 1A output.

Visual Charge Confirmation

The integrated LED illuminates whenever the solar panel is actively delivering current to the battery, providing instant visual confirmation that the electrical connection is secure and the panel is successfully capturing energy. During nighttime hours or periods of insufficient light the LED remains off to indicate no charging current is flowing — eliminating any guesswork about whether your solar system is working.

Compatibility & Important Notes

Compatible with 12V and 24V charging configurations and rated for panels producing less than 1 ampere of output — a range that generally does not pose an overcharging risk to deep cycle marine batteries. When installing, always pair a 12V panel with a 12V battery and a 24V panel with a 24V battery to maintain system integrity.

Note: This device is a monitoring indicator only — it is not a solar charge regulator and does not provide overcharge protection. For applications requiring battery level indicators and automated overcharge protection, an advanced Solar Charge Regulator is recommended.
