About this item
- SMART PWM TECHNOLOGY: The controller compatibility with 12V and 24V system, Discharge Current: 30A; dual USB output 5V / 2.5A, Build-in industrial microcontroller for automatical management, memorizing various parameters set by the user and the data won't be lost when the battery runs out, suitable for lead-acid batteries: OPEN, AGM, GEL. Controller mode: b1: lead-acid. b2: ternary lithium. b3: Lithium iron phosphate
- FUNCTIONAL LCD SCREEN: Easy to install and operate, Intuitive LCD display that can clearly indicate the status and data is able to switch modes and parameter configuration, The level of complete power-off is adjustable, which can perfectly protect the lithium battery from over-discharge, suitable for home, industrial, commercial etc
- 3-STAGE PWM CONTROL CHARGING: Fully 3-stage PWM regulation charging using direct charge, lifting charge, floating charge three-stage PWM regulation charging mode. Using the controller to realize efficient and fast intelligent charging, and effectively prolong the service life of the battery
- MULTIPLE INTELLIGENT PROTECTION: Built-in overcurrent protection, short circuit protection, reverse connection protection, open circuit protection, all automatic recovery, no damage to the controller, a reliable protector for your devices. If the battery voltage is lower than 8V, the solar controller will automatically shut down to protect the battery life
Product Description
Something You Need to Know !
Pre-sales
1. It can ONLY work with Lead Acid Batteries: OPEN, AGM, GEL. NOT for Nickel Metal Hydride, Lithium ions, or other batteries.
2. The PWM controller can ONLY accept DC power and is unsuitable for AC power.
3. Max.PV Voltage: 50V (12V battery for 15-23V solar panel, 24V battery for 30-46V solar panel).
4. Max.PV Input Power: 390W(12V), 780W(24V).
5. Compatible connecting wires: The connecting port has a large section and spacing that can install 6mm wire. (The wire is NOT included).
6. The PWM controller does not have a constant voltage function, and the load end output of the controller cannot remain between 12-13V.
7. Do not support viewing how much amps you're getting off your solar panel.
Sales Questions
Q1: Why is it can not get a display of 13.2volt? 18volt solar panel voltage, 12volt lead acid battery(good battery), followed exactly the instructions listed, but it displays 12.5volt only.
A1: Please check the battery voltage. If the battery is fully charged, it will display 14.4 volts.
Q2: When l hook up the solar, it does not show charging. When I put a meter on the controller solar input, it shows the polarity is reversed. Could this be a mistake in how the unit was connected internally?
A2: Yes. In this case, please check if the battery is correctly connected to the solar controller.
