CyboEnergy, Inc. announced today that it has released the off-grid CyboInverter H model, which is specially designed to power electric water heaters or electric heating elements.
Most electric water heaters on the market have 2 heating elements, called dual-element or double-element water heaters. In the US, AC from a standard 30A branch circuit with 240V is connected to the water heater to supply power. An off-grid CyboInverter is connected to deliver solar energy to the lower heating element. The temperature setpoint for the lower element can be purposely set much higher than the upper element. This way, the upper element that consumes grid power does not turn on unless a lot of hot water is used within a short period of time. Because the grid power can heat the water quickly from the upper heating element, hot water will always be available. Connecting the CyboInverter output to the lower heating element is easy, the company reports, and the steps are well documented in the CyboInverter H Model Installation Guide.
Cyboinverter is a patent pending solar power Mini-Inverter possessing the key merits of both central inverters and microinverters. The CyboInverter H Model can connect to 4 solar panels and generate up to 1150W AC power. Each CyboInverter's input channel has its own control and maximum power point tracking (MPPT) mechanism so that power production is maximized and the partial shading problem is eliminated. The off-grid CyboInverter H model has the following unique features and benefits: <
- Specially designed for powering dual or double element electric water heaters,
- Reduces electricity bills, avoids high tier rates, and provides quick ROI,
- Has no high-voltage or high-current DC so that it is intrinsically safe,
- Ideal for battery-less off-grid solar systems,
- Easy installation and great price,
- High efficiency and long life, and
- Offers a much simpler solution than solar thermal water heaters.
A simple 1.2KW off-grid solar power system includes one CyboInverter H model and four 250W to 300W solar panels. In most areas, it can generate about 6KWh to 8KWh usable solar energy daily for electric water heaters with heating elements ranging from 1000W to 5000W. Depending on the installation site and local electricity rates, return-on-investment (ROI) can be achieved in 2 to 4 years. CyboEnergy received the Frost & Sullivan's 2013 Global Product Differentiation Excellence Award in Solar Inverters.
