<b>Features:</b></br>*30A Solar Charge Controller: Build-in industrial micro controller, automatically manage the working of solar panel and battery in a solar system.</br>*LCD Display: clearly indicate the status and data, it can be conveniently switched modes and parameter configuration, parameters adjustable.</br>*Safe to Use: It has short-circuit protection, open-circuit protection, reverse protection, over-load protection, and fully 3-stage PWM charge management, improve system efficiency and prolong the life span of the battery. </br>*Easy to Install and Operate: (1)Battery --->(2)Solar Panel ---> (3) Load. </br>*with Timer Function: You can set the on/off and a certain number of hours as you like, without extra worry, it is convenient for your life.</br></br><b>Specification:</b></br>Type: Solar Charge Controller</br>Battery Voltage: 12V / 24V</br>Charge Current: 30A</br>Working Temperature: -35℃ - 60℃ / -90℉ - 140℉</br>Self consume: 10mA</br>Float Charge: 13V</br>USB output: 5V/2.5A</br>Overcharge Protection: 14.4V/28.8V</br>Overcharge Floating charge: 13.7V/27.4V</br>Charge recover voltage: 12.6V/25.2V</br>Over-discharge Protection: 10.7V/21.4V</br>Max input power and voltage: 390W /12V; 780W/24V</br></br><b>Q&A</b></br>1.Q: How to install it?</br>A: The charge controller should connect the battery first, then the solar panel, and finally the load. The disassembly sequence is contrary to the wiring order.</br></br>2.Q: Without using a battery, can it be wired to an inverter and work directly from that?</br>A: Sorry no. A solar panel can't run an inverter without a battery.</br></br>3. Q: What type of battery do I need?</br>A: The charge regulator is only suitable for lead-acid batteries: OPEN, AGM, GEL, it is not suited for nickel hydride, lithium, Li-ions, or other batteries.
