Product Introduction

Brief introduction

A MPPT( Maximum Power Point Tracking ), or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.

Compared to conventional PWM controller, MPPT technology increases the charge efficiency up to 20% and potentially decrease the power of solar array needed.

Installation Procedure:

Step 1, Choose Mounting Location

Install the Charge Controller in an upright position out of direct sunlight, high temperature, and water.
Step 2, Check for Clearance
Place the mppt controller in the location where it will be mounted. Verify that there is sufficient room to run wires and that there is sufficient room above and below the controller for air flow.

Step 3, Mark Holes
Use a pencil or pen to mark the four mounting hole locations on the wall (mounting surface)
Step 4, Drill Holes
Remove the Charge Controller and drill four size able holes in the marked location.
Step 5, Secure Controller
Insert all W 5/ 16-18 sheet metal screw through each hole and tighten against the wall.

Q: How many charging mode does the controller have?

A: There are two charging modes. There are PWM and MPPT. MPPT is the most advanced. Felicity have already developed MTTP charge controller with high performance, reliability, efficiency and fast tracking speed.

Q: What's the difference of the PWM charge controller and MPPT charge controller?

A: 1. MPPT controller uses maximum power tracking technology, compared to the PWM controller, the MPPT can generate more electricity with the same solar panels.

     2. MPPT controller has low requirement of solar power system voltage, if the line or component parts damage the voltage, using MPPT controller does not affect the system generating. 

     3. MPPT controller can detect the temperature of the battery, then adjust the temperature by itself, the solar panel can  charge the battery more efficiency.

Q: Why should the controller have temperature compensation function?
A:  As temperature rises, electrochemical activity in the battery increases. Similarly, as temperature falls, electrochemical activity decreases. Therefore, as temperature rises, charging voltage should be reduced to prevent overcharge, as temperature falls, charging voltage should be increase to avoid undercharge. In general, to assure optimum service life, use of a temperature compensated charger is recommended.

Q: How does your factory carry out quality control?
A: Quality is our priority. Our QC always attached great importance to quality control from the very beginning to the end of the production. Each product will be fully assembled and carefully tested before packed.

Q: What is the warranty for MPPT Charge Controller FL-CSM6048?

A: For the charge controller, we offer 2 year warranty.
Q: What is MOQ for inverter?
A: MOQ is 1 PC or mixed.
Q: What is the terms of payment?
Q: T/T, L/C, Western Union, PayPal or cash; 30% for deposit, the balance 70% before shipment.
Q:What is the delivery time?
A: 3 work day with stock after receiving the payment. No stock, 25 work days after receiving the payment.
