It also provides interactive charts and reports to help you visualize production and energy consumption over the life of the system. The monitoring provides fault detection and active alerts about the health of your system. SolarEdge offers a full-featured monitoring portal to help you view and manage the production from your system, as well as each individual panel. This failsafe makes installation way less scary and more approachable for someone looking to DIY install. There’s no shock risk because the wires aren’t electrified until the system runs checks to ensure it is set up properly. The optimizers prevent your panels from producing more than 1 volt of power until everything is hooked into the inverter and the system has been tested and commissioned.Įssentially, the inverter will verify it has been wired correctly before it starts to produce power. The HD-Wave has some other great safety features as well.

The code is in place to ensure the safety of emergency responders-for example, firefighters would not have to worry about shutting down the array before putting out a fire on the property.Īn HD-Wave with the rapid shutdown safety feature. This is a safety measure that automatically shuts down your array in the event of a power outage. Optimizers make the HD-Wave compliant with the rapid shutdown requirements outlined in the latest National Electric Code (NEC 2017 690.12). This keeps the inverter in a voltage range that allows it to operate at peak efficiency. In addition, the HD-Wave can call on the optimizers to boost the voltage coming from other panels to compensate for the underperforming panel.
Reduced output from one panel doesn’t translate to the rest of the string. Panels that underperform (due to factors like shade, poor orientation, or equipment malfunction) are isolated thanks to the optimizers. The HD-Wave’s power optimizers solve this problem.īy attaching an optimizer to each panel, your inverter will monitor each panel separately and make any adjustments necessary to keep the system producing at an optimal level. An issue with a single panel causes a 25% production drop across the array. You may own a string of ten 330W panels, but if shade falls on one panel and drops the output to 250W, all ten panels in the string will produce 250W apiece. The main selling point for the HD-Wave is that the power optimizers allow the inverter to monitor and optimize the output of each panel independently.Ĭlassic string inverters like the Sunny Boy have a major limitation: if the output of one panel in a string drops, every panel in the string drops to match the reduced output.
And for systems that are 6-8 panels or larger, the HD-Wave costs less than an IQ7+ micro-inverter system. The optimizers ensure you are getting as much production as possible from your panels, making it versatile enough to work with almost any system. The HD-Wave is our “one-size-fits-all” inverter that strikes a balance between budget and efficiency. The power optimizers mitigate shade and other production drop issues better than the Sunny Boy, and it’s more cost-effective than buying IQ7+ micro-inverters for every panel (especially on a large scale). Read our IQ7+ review.įor all other systems, we turn toward the HD-Wave as our go-to recommendation.
If your system won’t suffer shading or other production drop issues, the Sunny Boy is the most cost-effective option.The HD-Wave is one of three inverters we recommend with our grid-tie systems, alongside the SMA Sunny Boy and Enphase IQ7+ micro-inverters.īoth of the other options have specific use cases:
