1. What does MPPT mean, and how does the SOL30 use it?

MPPT stands for Maximum Power Point Tracking. The SOL30 continuously monitors the photovoltaic module and adjusts its operating point as solar intensity changes. This enables the controller to use the available solar energy efficiently when powering the load and charging the battery.

2. Does the SOL30 support both 12 V and 24 V batteries?

Yes. The SOL30 automatically detects whether the connected DC-UPS has been configured for a 12 V or 24 V battery system. Its output range is 10–14.4 Vdc for 12 V batteries and 22–28.8 Vdc for 24 V batteries, with a nominal charging current of 1.3 A.

3. Which battery types can be charged using the SOL30?

The SOL30 can support open lead-acid, AGM, gel lead-acid, Ni-Cd and lithium-ion batteries. The charging parameters are defined by the connected ADEL System DC-UPS and transferred automatically to the SOL30 through ADELBus.

4. What solar panel input does the SOL30 require?

The SOL30 accepts a PV module open-circuit voltage from 12–35 Vdc and can withstand up to 45 Vdc for one minute. The specified minimum PV module power is 30 W. The correct panel specification should be confirmed against the complete system load, battery and environmental requirements.

5. Can the SOL30 be monitored and configured remotely?

Yes. The SOL30 uses ADELBus CAN communication to connect with a compatible ADEL System DC-UPS. This enables monitoring, recording, configuration and firmware updates through the DC-UPS web server. When connected to the CBI60, it can record up to ten days of detailed power and load data.

SOL30

The SOL30 is a compact MPPT solar charge controller developed to connect photovoltaic modules to compatible ADEL System DC-UPS solutions. It uses Maximum Power Point Tracking to maximise energy harvested from the solar panel while supplying the load and charging a 12 V or 24 V battery system. The controller delivers a nominal battery charging current of 1.3 A and accepts a PV open-circuit voltage from 12–35 Vdc. ADELBus CAN communication enables automatic battery configuration, remote monitoring and adjustment through the DC-UPS web server. Its fanless DIN rail or wall-mount design, 91% peak efficiency and integrated electrical protections make it suitable for off-grid power, industrial control, remote monitoring, security and solar lighting systems.
