30A 12V/24V PWM Solar Charge Controller with LCD Display and USB
Control charging in a small solar battery setup with this RTD1230 30A 12V/24V PWM Solar Charge Controller, designed to sit between a suitable solar panel and battery system.
The controller is marked for 12V/24V 30A USB operation and has a built-in LCD display for checking system information. The front connection area includes screw terminals for battery, solar panel and load/output wiring, plus a single USB Type-A output port for suitable 5V devices.
This is a practical solar regulator for low-voltage direct current projects such as caravan solar, camping power, shed lighting, small battery charging systems and other basic off-grid solar setups. Key Features

• Connect the battery first so the controller can detect the system voltage correctly
• Then connect the solar panel
• Then connect the load/output if required
• Use a suitable direct current fuse or circuit breaker on the positive cable between the battery and controller
• The fuse should be installed as close to the battery as practical
• Always size the fuse to protect the cable, not just the controller
• Use correctly rated direct current cable, terminals and fuse hardware
• Installation should be carried out by someone familiar with low-voltage direct current solar wiring Frequently Asked Questions (FAQs): Is this an MPPT solar controller?
No. Thi
