Product Description

What is a Micro-Inverter? Several other companies in the solar industry have followed suit and launched their own micro-inverters, validating their potential. Evergreen is always on the crest of the wave, so we have also launched our best model with great quality and all approvals to be used in any geographical market. Central inverters have dominated the solar industry since its inception. The introduction of micro-inverters marks one of the biggest technology shifts in the PV industry. Manufacturers are touting 5-25% increase in power output, which in the long run can bring in a lot in savings for many homeowners.
Our company develops and markets world leading, highly reliable grid connected solar micro-inverters and monitoring systems that offer an outstanding value proposition for solar PV systems. The micro-inverter converts and controls the DC power from each solar module into clean AC power for supply to the electricity grid.

The advantages of our EVERGRID MI Series solar micro-inverters include:
-        Maximized energy harvest,
-        Improved safety,
-        Increased lifetime and reliability,
-        Enhanced monitoring capability, and
-        Simplified PV array design and installation.
The monitoring system tracks, in real-time, each PV modules performance through a robust built-in wireless communication system that connects to the Internet via a Gateway (PLEASE CHECK FOR OUR GATEWAY MODEL IN OUR WEBSITE).
Since solar panels generate DC (direct current), we need some kind of device to convert DC to AC (alternating current), in order to power your electrical appliances (without burning down your house!). This is where the solar inverter comes in. Inverters also enable us to switch off all electrical current in the case of a blackout or if repair is needed. This is of course also useful for maintenance, troubleshooting and system upgrade as well. One central (string) inverter would normally cover an entire residential solar system (assuming that the central inverter is strong enough for your entire array). Micro-inverters, on the other hand, sit on the back of each and every solar panel. Micro-inverters bring several significant benefits to the table. Do these benefits outweigh the extra costs? Let’s see….
Key Benefits
Individual Optimization. Micro-inverters optimizes for each solar panel alone, not for your entire solar system, as central inverts do. This enables every solar panel to perform at their maximum potential. In other words, one solar panel alone cannot drag down the performance of entire solar array, as opposed to central inverters that optimize for the weakest link. Shading of as little as 9% of a solar system connected to a central inverter, can lead to a system-wide decline in power output with as much as 54%. If one solar panel in a string had abnormally high resistance due to a manufacturing defect, the performance of every solar panel connected to that same central inverter would suffer. Likewise, coverage issues such as shading, dirt, snow and even slight orientation mismatch on one of the solar panels would not bring the entire solar system down.
Maximum Power Point Tracking (MPPT).One of the tricky things about solar cells is that voltage needs to be adjusted to light level for maximum output of power. In other words, the performance of a solar panel is dependent on the voltage load that is applied from the inverter. MPPT is a technique used to find the right voltage at the maximum power point. When MPPT technique is applied to each individual panel, as opposed to the solar system as a whole (central inverter case), performance of the whole system will naturally improve.
Longer Warranty. Since micro-inverters are not exposed to as high power and heat loads as central inverter, they also tend to last significantly longer. Micro-inverters typically come with a warranty of 20-25 years (10-15 years longer than central inverters).
Easily Expandable. Expanding your solar system with more solar panels later on is easier with micro-inverters. You do not have to worry about restringing or getting a second central inverter installed. Central inverters come in limited sizes and you might end up having to pay for one that is much bigger than what you actually need.
Performance Reports. Web-based monitoring on a panel-by-panel basis is usually available both for homeowner and installer. Continuously analyzing the health of the solar system can pave the way for additional tweaks and performance improvements. There are even mobile applications that enable you to monitor your PV system when on the road.
No Single Point of Failure. Unlike central inverters, if there is something wrong with either one of the solar panels or the micro-inverter that sits on the back of it, the rest of the solar system is unaffected and still up and running.
Improved Safety. Solar panels are connected in series before they are fed into a central inverter, typically with an effective nominal rating of 300-800 VDC (volts of direct current). This current is potentially life threatening. Micro-inverters eliminate the need for high voltage DC wiring, which improve the safety for both solar installers and system owners.
Silent. Since micro-inverters dissipate significantly less heat than central inverters do, there is no need for active cooling, which enables them to operate without noise.
Cost Analysis is Necessary. We evaluate the usefulness of micro-inverters by looking at two numbers:
- Lifetime costs ($)
- Lifetime energy production (kWh)

This is essentially what it all comes down divide costs by energy production and you`re left with how much money you have to pay for every kWh your solar system produce. Every situation is different and there are a lot of variables to take into account in order to find those two numbers.
One of the leading micro-inverter manufacturers sums it up nicely: “A total cost of ownership analysis of a PV solar system can only be carried out after detailed examination of capital and maintenance costs, and an understanding of how much energy will be harvested over the life of the system”.
