When solar end users ask for backup power, they typically want to back up their most critical loads, not their whole home. That still leaves installers with a maze of components, utility coordination and compatibility concerns as they try to manage solar generation, battery storage and grid power. What if there was a way to give end users only what they need with one smart unit that manages solar, battery and grid power?
That’s where the Hoymiles hybrid solar inverter for backup power comes in—offering a smart way to manage solar, battery, and grid power in one unit.
Watch Ethan demonstrate the Hoymiles hybrid solar inverter features, or explore five reasons this partial home backup solar solution is a game-changer.
Hoymiles Partial Home Storage Solution
Ethan Wollbrink from Van Meter introduces a 7.6 kW hybrid solar inverter designed for partial home backup solar solutions. This hybrid solar inverter features a built-in transfer switch, delivering continuous power of 40 amps at 240V AC for essential circuits. It can be paralleled with up to ten units, with common sizes being 7.6, 9.6, and 11.5 kW. Additionally, this solar inverter with low-voltage battery compatibility supports up to ten batteries per unit, giving installers flexibility. More details about this device will be shared in future videos.
1. BUILT-IN TRANSFER SWITCH
The Hoymiles hybrid solar inverter with built-in transfer switch delivers continuous 40 amps at 240V AC, simplifying installation. That means solar installers don’t have to install a separate transfer switch or coordinate a grid shutdown with the utility to install it. This reduces complexity and cost for the installer and end user.
2. CRITICAL LOAD PROTECTION
This hybrid solar inverter for critical load protection acts as a partial home backup, ensuring essential circuits stay powered. During a power outage, the built-in transfer switch will automatically switch power over to the battery. The continuous 40 amps is enough to power critical loads like refrigerators, lights and medical devices.
If there is sunlight available, the hybrid solar inverter can continue to use solar power to charge the battery and power loads.
3. FLEXIBLE BATTERY COMPATIBILITY
This inverter has a low voltage battery connection, and the approved battery device list is pretty comprehensive. Systems that rely on a proprietary battery are only as good as the longevity of the manufacturer. With this system, you’re not tied to a specific manufacturer, and you can pivot if necessary.
Flexible Battery Compatibility
Freedom to Choose and Adapt
The Hoymiles Hybrid Solar Inverter connects to low-voltage batteries and supports a wide range of approved devices. Unlike systems locked into proprietary batteries, this inverter gives you flexibility. If a manufacturer changes or exits the market, you’re not stuck—you can pivot to another compatible option without replacing your entire system.

4. SCALABLE HYBRID SOLAR INVERTER OPTIONS FOR LARGE SYSTEMS
It’s a scalable hybrid solar inverter solution, ideal for large homes or commercial setups where energy storage needs grow over time. If one inverter isn’t enough to power everything you need, you can parallel up to 10 inverters. Each inverter can have 10 batteries. That means a system could potentially scale to 100 batteries total. It’s good to have the flexibility in large homes or commercial setups where energy storage needs may grow over time.
5. MINIMAL WALL SPACE REQUIRED
Installing this partial home backup system only requires three components, the inverter, battery and critical loads panel. Having an internal transfer switch instead of a separate device means one less component on the wall. Instead of wiring the inverter to a full secondary panel, installers only need to install a small critical loads panel for essential circuits.
By consolidating multiple functions into a single, compact system, installers can streamline installs and reduce footprint.
