Why Choose This Kit?

2kWh Capacity for Real Home Backup

With 2048Wh capacity, DELTA 3 Max is much better suited for home backup than a basic 1kWh power station. It gives users more usable runtime for essential devices during outages, especially when powering multiple items at the same time.

This kit is suitable for:

• Refrigerators
• Wi-Fi routers
• Phones and tablets
• Laptops
• LED lights
• Small fans
• CPAP machines
• Emergency electronics
• Small kitchen appliances
• RV and camping equipment

For customers who want a more serious backup setup without moving into a whole-home system, this is one of the strongest mid-size options in the DELTA 3 lineup.

400W Solar Panel for Faster Daytime Recharging

The 400W solar panel is the key upgrade in this kit. Compared with a 220W solar kit, the 400W version can collect more solar power under good sunlight conditions, helping users recharge faster during the day.

This is especially valuable for:

• Longer outages
• Storm preparation
• El Nino-related weather uncertainty
• RV trips
• Camping
• Off-grid use
• Customers who do not want to rely only on stored battery power

The message for customers is simple:

2kWh gives you more stored power. 400W solar helps you recover that power faster during the day.

Stronger Output for More Home Essentials

DELTA 3 Max delivers 2400W output, giving it more flexibility than many 1kWh-class power stations. It can support a wider range of household essentials and small appliances, depending on each device’s wattage and startup requirements.

This makes it a strong choice for customers who want more than phone and laptop backup.

Clean Indoor Backup Without Gas

Unlike gas generators, this kit does not use fuel, does not produce fumes, and can be used safely indoors. That makes it especially useful for:

• Apartments
• Condos
• Homes
• Bedrooms
• Home offices
• RVs
• Indoor emergency backup

It is a cleaner, quieter backup option for modern households that want power security without generator noise or fuel storage.
