Enphase Micro-Inverters:

At the heart of Enphase system is a powerful technology. Solar panels may be on top, but it’s the inverter that does all the real work. Choosing an inverter technology is the most critical decision you will make while going solar.

Enphase micro-inverters make use of the highest quality components, cutting edge technology and advanced monitoring software to create tailored solar energy solutions for Homeowners and commercial projects.



  • Higher production and best Savings

Enphase microinverters are proven to produce more energy than other technologies. Microinverters operate independently, so each panel performs to its fullest. One shaded or dirty panel won’t affect the rest of the system. Burst technology lets microinverters produce more at dawn, dusk, and in low-light conditions, for a longer solar day.

  • Reliable

Enphase micro-inverters function independently and are inherently more reliable: as there is no single point of failure in a microinverter system.

  • Safety

Enphase are well known for meeting the requirement of safety norms as they Micro-inverters provides for an all A/C current at a lower voltage compared to traditional inverters with a high voltage of DC current.

  • Flexibility

The Enphase System is flexible, so you can design a system to fit today’s budget and energy needs, and expand it later as your needs evolve

  • Higher Production Efficiency

Enphase tolerates shading better than conventional inverters. Secondly, their independency of micro-inverters maintains operation of your system although part of panels is affected by shading, dirt or leaves. With micro-inverters, only the individual panel is affected (by either shade or debris), while the other panels perform to their maximum efficiency. With string panels, if one panel is affected, the other panels operate at the same diminished capacity.

Photovoltaic Panel

How it Works?

Photovoltaic Panel

Step 1: The solar panels on your roof absorb sunshine in the form Direct Current (DC) power. Fixed beneath each panel, a Micro-inverter converts the DC power into Alternative Current (AC), the form of electricity your home can use.

Step 2: The Envoy is the brain of the system, gathering data from your micro-inverters and delivering it to the Enlighten software. It communicates in the other direction also allowing to pinpoint any issue remotely and delivering updates to the micro-inverters.

Step 3:My Enlighten is your window into your home energy. It turns Envoy’s data into an easy to use interface that lets you track your system’s production and see your home energy usage.

Photovoltaic Kit and SSDG Net-Metering Scheme for Residential requirement

The installation of Photovoltaic Kit for residential requirement need to abide by the SSDG Net-Metering Scheme set by the CEB. All Installations will be equipped with one production meter and one import/export meter.

If a Prosumer take more electricity from the CEB than she/he has sent into the grid, the quantity imported in excess of the quantity exported will first be reduced by any quantity of energy already in balance, if any, before the final energy charge is raised.
Sizing of the Photovoltaic Kit

The size of the Photovoltaic Kit for residential installation is as from 1 KW till 3.5 KW as established by the CEB.

Photovoltaic Project and MSDG Net-Metering Scheme for Commercial requirement

For installation of On Grid Photovoltaic system for commercial requirement; the project proposal should meet the criteria of the MSDG Net-Metering Scheme of the CEB.

Off Grid Photovoltaic System

For the requirement of producing electricity without being dependent on the Grid, Duraco Ltee provides off grid solution, through Western Co. Ltd , an Italian based specialist of Off Grid solutions.


Our PV Panels are of 310 Watts capacity as referred in the On grid section. Based on the regions and the load being used, our Engineers will design and calculate the Quantity of panels required to meet the site requirement.


MPPT Charge Controller

MPPT Charge Controller

WRM are the solar charge controllers of the western series with MPP Tracking. They can be used either in small or big systems for domestic and industrial use and for telecommunication systems. They control the current of PV modules with PWM recharge and the battery discharge disconnecting the charge in case of deep discharge of the battery. Different configurations are possible: load always on, load on only during the day, load on only during the night, load on only during the night that can be programmed for a total number of hours from 1 to 16.


  • MPPT (Maximum Power Point Tracking) Algorithm – Enables efficient transfer of energy from cells to the Inverter
  • LCD Graphic display
  • Light Sensor Function to optimize energy conversion


Off Grid Inverter

Leonardo Series – Made in Italy

Leonardo Series - Made in Italy

Leonardo Inverter Series are integrated inverters able to manage, control and complete different sources of renewable energy.

Battery Systems for storage

Batteries in solar applications have to meet the demands of unstable grid energy, heavy cycling (charging and discharging) and irregular full recharging. There is a variety of battery types fitted for these unique requirements. Considerations for choosing a battery include cost, cycle life and installation and maintenance as per table below:
