MicroBLOX HES-MB-520

Our popular MicroBlox HES-MB-500B is a 520W building block used to customize any size of grid-tie system. The modular approach allows homeowners to start with a smaller system and expand later.
On a sunny, south-facing roof, each HES-MB-520 will generate 520-670 kWh of electricity per year, displacing 5% of a typical home's electrical consumption or 10,000 kWh per year. Popular systems are 4 HES-MB-520 (20% of a typical home's use) and 10 HES-MB-520 (50% of a typical home's use).
