1.0 General Information
1.1 Overview
Thank you for selecting the MPPT solar charge controller.The MPPT is essentially a smart DC to DC converter which has been optimized to harvest maximum energy from the PV array in battery based solar electric systems by using a variety of maximum power point tracking (MPPT) strategies. The controller’s secondary objective is to ensure that the batteries receive a full charge without becoming overcharged. This is accomplished through a four stage charging process. Please take the time to read this operator’s manual and be familiar with the controller.This will help you make full use of the many advantages the MPPT can provide for your PV system.
1.2 Features
1 - Battery Status LED Indicator:An LED indicator that shows battery status or system errors.
2 - Charging Status LED Insdicator:An LED indicator that shows charging status and overvoltage of pv.
3 - Setting Button1:Set load work mode,battery type and max charge current.
4 - Setting Button2:Set load work mode,battery type and max charge current(in manual mode used for load ON/OFF).
5 - LCD Digital Display:Dispaly the system status
6 - Wiring Box Cover:Sheet metal wiring box cover protects power connections
7 - FAN:FAN to dissipate Internal circuit heat
8 - Heatsink:Aluminum heatsink to dissipate controller heat
9 - Mounting Hanger:Keyhole slot for mounting
10 - Solar Module Terminals:Connect solar modules
11 - Battery Terminals:Connect batteries
12 - Load Terminals:Connect loads

13 - RJ45 Communication Interface:Communicate with personal computer

2.0 General Information
The mounting location is important to the performance and operating life of the controller. The environment must be dry and protected from water ingress. If required, the controller may be installed in a ventilated enclosure with sufficient air flow. Never install the MPPT unit in a sealed enclosure. The controller may be mounted in an enclosure with sealed batteries, but never with vented/ flooded batteries. Battery fumes from vented batteries will corrode and destroy the MPPT circuits. Multiple MPPT can be installed in parallel on the same battery bank to achieve higher charging current. Additional parallel controllers can also be added in the future. Each MPPT must have its own solar array.
CAUTION: Equipment Damage or Risk of Explosion
Never install the MPPT in an enclosure with vented/Flooded batteries. Battery fumes are fl ammable and will corrode and destroy the MPPT circuits.
CAUTION: Equipment Damage
When installing the MPPT in an enclosure, ensure suffi cient ventilation. Installation in a sealed enclosure will lead to over-heating and a decreased product lifetime.
NOTE : Mounting
When mounting the MPPT ,ensure free air through the controller heat sink fins. There should be at least 150mm of clearance above and below the controller to allow for cooling. If mounted in an enclosure, ventilation is highly recommended.

Q:Solar controller 10a, a represents what
A, represents the current. Indicates the current that is allowed to pass during operation of the controller.
Q:What is the meaning of the DC load above the solar controller?
Can be batteries, lights, motors and other DC equipment can be used
Q:What is the power of the solar controller?
The solar controller is represented by the maximum available current
Q:Solar controller water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
Q:How the inverter is connected to the solar controller
No, no load will not work!
Q:How to adjust the solar controller
The controller through the computer chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity of the sample, through the special control model calculation, to achieve the characteristics of the battery discharge rate, temperature compensation correction of high efficiency, high accuracy rate control , And adopted a high efficiency PWM battery charging mode, to ensure that the battery work in the best condition, greatly extending the battery life. With a variety of work patterns, output mode selection, to meet the various needs of users.
Q:Solar controller use
The controller as a core component of solar energy must be a reliable product, otherwise no matter how good the solar system can not play its due role.
Q:Solar controller one machine how
Built-in high-precision step-up constant current source, no need to reprovision LED constant current source, can directly drive LED lamp beads, single string up to 18, up to 9 groups in parallel, the output power can reach 160W, to meet all the market LED street lamps;
Q:What is the meaning of the 30A solar controller?
Control the superscript of the current should be in accordance with the rated current to the target, rather than the maximum current. That is: the other side of the discharge or charge when the rated current is 30A. If you explain the controller is the maximum current, the basic is substandard products.
Q:Solar controller does not heat how to heat
Solar energy itself is the hot water of the stuff, certainly can be heated, but not with electric heating only.
