HMB Solar – building energy resilience with reliable energy storage and monitoring solutions

Posted on:

Venezuela, the country with the world’s largest oil reserve, relies heavily on oil and hydropower to generate electricity. In recent years, residents, especially those in rural areas, have been experiencing unreliable grids. To overcome the issue, HMB installed a backup power system using Schneider Electric’s residential solar and storage solutions.

 

Challenges

Venezuela is one of the world’s leading exporters of oil with large reserves of oil and gas. With one of the cheapest electricity costs in the world, it has a strong dependence on oil and hydropower for the generation of electricity. However, in recent years, Venezuela is experiencing instability and lack of reliability in its electrical power system.

This problem is more prominent in rural Venezuela, including its households, small health centers, and schools. In many cases, people only have diesel and gas generators as an alternative power source in these areas.

With the recent advance in Photovoltaic technology, HMB Solar helps residents reduce the impact of fluctuating power and outages by being energy independent, producing their own energy in a cost-effective way. Additionally, HMB Solar comprehends the global goal of reducing greenhouse gases and wants to be an active part of the solution.

 

Solution

HMB Solar designed a 4 kW DC-Coupled grid-interactive hybrid system that includes a string array with 12 panels roof-mounted mono with perc technology with total power of 4,620W and an integrated lead crystal battery bank with a capacity of 220Ah at 48 volts. The installation included the following solutions from Schneider Electric:

  • 1x Conext™ SW 4048 120/240 inverter/charger
  • 1x Conext™ MPPT 80 600 charge controller
  • 1x Conext™ Gateway
  • Conext™ Insight 2
  • 1x Conext™ System Control Panel
  • 1x Conext™ SW AC Power Distribution Panel
  • 1x Conext™ SW DC Power Distribution Panel

The Conext™ SW inverter/charger, together with Conext™ MPPT solar charge controller, provided a robust and reliable solution for small and medium residential and rural installations with different types of loads. Working as an off-grid or backup power system, the enhanced grid support feature allows for harvesting the maximum power available from the sun without affecting the power quality delivered to the loads.

 

Conext™ Gateway and Insight 2 for monitoring and remote management

This type of installation could be implemented in isolated areas with limited access for a rapid response to any issue faced by the end client. The Conext™ Gateway is the ideal solution to achieve remote connectivity with full access to the system. It also allows clients to feel confident that HMB Solar would give them a timely response.

As a system integrator, HMB Solar finds that Conext™ Insight 2 is a powerful tool for multi-site management. Conext™ Insight 2 is a cloud-based energy management platform where all HMB’s solar projects are stored in a centralized repository, allowing remote access from any location.

 

“From the moment of installation, our life has changed. We can now lead a normal life knowing that we have an automatic, reliable and environmentally friendly energy system in case of electrical outages”
