The modern solar industry was through off-grid solar, a market born, remains an important aspect of the industry. Around the world one power of live six people out of reach, but they can rely on off-grid solar power systems. In North America the off-grid solar is especially popular for building in remote areas where the utility grid is not yet reached, or in places, the vulnerable to storms and power outages.
Off-grid solar systems are less common than grid-tie systems for a number of reasons. An off-grid system requires other components such as batteries and charge controllers. With additional components installation is more complex and requires a higher level of technical training. It is also more expensive for the end user, and not all end-user need solar off-grid.
Although grid more complex than grid tie and off-grid market continues to grow there is a shift with experienced installers are beginning to move from the competition-grid-tie market in the more lucrative grid market. Solar product suppliers also work to facilitate off-grid systems. Pay attention to the following offerings:
Off grid packages
Mains-independent system integrators can reduce the complexity of an off-grid system, by providing easy-to-install packages. A package can contain an inverter/charger, solar charge controllers, controls and accessories. The components should work all together, if you take them out of the box. A mains-independent ordering system, such as a package also ensures that all necessary parts are together and superfluous, plunge to contact the suppliers from a construction site to a forgotten part.
Flexible off-grid inverter
Another way, which is to reduce complexity of the off-grid solar projects to find a charger/inverter, the flexible enough to all installation requirements. Search for inverters with intelligent load management to handle a diverse set of energy loads. Load management is incredibly important if you connect your inverter to a generator or the utility network. Some inverters have dual AC input of the generator and the grid, which lowers the additional component system requirements and provides more flexibility for different system requirements take up. Connecting an off-grid solar system to the utility power grid (where possible) end user also gives you the opportunity to sell back excess energy to their energy supplier.
Stackable off-grid inverter
Creating an off-grid solar system requires a large up-front investment. It is common for homeowners with a smaller system, with plans to later add to start. Adding more is solar easy when you start with an inverter, which can be stacked together with other inverters. An existing grid tie solar-system it is an off-grid solar power inverter also increasingly by AC coupling. A grid-tie solar system is great, but it requires electricity to operate and turns any utility power outages. Off-grid inverter coupled with batteries only uninterruptible power supply will provide for critical loads.
As mentioned previously, off-grid suited to solar systems for building remote sites. Remote sites require additional travel time to reach. Select to return visits to inverter, which have proven reliability and lasts for years. Trust suppliers who were successful financially in the broiler market for many years. Ask for references for older systems, or show you how to test the product internally.
If service is necessary, it is important that the supplier for the troubleshooting and enable quick resolution will be available. The supplier should reach the end user for emergencies. Troubleshooting enables new technology makes faster remote connections to the grid inverter. This can be done by a remote monitoring system. Search for systems that can upgrade firmware even from afar.
The off-grid solar market continues to grow, these offers will ensure that off-grid off-grid solar systems secure, reliable, and cost effective.
