[Upgraded] 30A Solar Charge Controller, 12V/ 24V Solar Panel Regulator with Adjustable LCD Display Dual USB Port Timer Setting PWM Auto Parameter Specification Item model number H0911-2 Display Type LCD Batteries required No Product Dimensions 5.28"L x 2.8"W x 1.3"H Country of Origin China Style 30A Item Weight 0.17 Kilograms Voltage 24 Volts Manufacturer Depvko Brand Depvko Included Components solar charge controller 2.8 "h x 5.28 "h x 1.3 "h. Weight: 0.17 kg ?UPGRADED SOLAR CONTROLLER?This solar charge controller helps you manage the working of solar panels and batteries in solar systems automatically with the build-in industrial microcontroller. You don't need to reset it when the battery runs out cause it will memorize various parameters set by the user ?WIDE COMPATIBILITY BY AUTOMATIC ADAPTATION?Compatible with 12V and 24V systems (automatic adaptation, depends on your systems's voltage, no manual adjustments required). A little amplitude voltage deviation is normal. You can also charge your mobile phone, tablet, and PC through the Dual USB output 5V/2.5A (max) ?COMPATIBLE BATTERY TYPE?This solar controller is ONLY suitable for various Lead-acid batteries (including open, sealed, colloid, etc.) Please DO NOT charge to lithium or nickel-metal hydride batteries, etc. Auto-recognizing battery voltage function can protect the battery from misuse and better control the charging process. Note: When installing the controller for the first time, please ensure the battery is fully charged to recognize the battery type correctly ?SAFE TO USE?With Intelligent protection against overcurrent, short-circuit, open-circuit, inverse, low voltage, and overcharge, all of which are automatic recovery types, do not damage the controller. It also has a dual MOS anti-backflow circuit and low heat. This 30A solar charge controller will help you improve the system efficiency and prolong the battery life. But still note to install the controller on a flat, well-ventilated surface ?LCD DISPLAY?Let you know the working status and data with the LCD. The regulator equips load time control and a manual setting function, so you can switch modes and configure parameters conveniently. A good choice for use at home, industrial, commercial, etc. See the instruction manual for specific parameter settings and adjustment methods ?HOW TO CONNECT THE SYSTEM??When installing, please install the battery first and then connect the solar panel. When disassembling, first remove the solar panel and then the battery. Please connect the devices as the instruction manual shows or the system may be damaged by misuse ?BUY WITH CONFIDENCE?12-month guaranty and technique support.

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. After-sales Service 12-Month After-sales Serviceand lifetime technique support.
