Sol-Ark's Sixth Generation of Hybrid Inverters

Whole Home Backup

• Combined battery plus solar power handling of 15kW
• A true whole home back-up in one box. Handles high (current or inductive) loads such as HVAC units and well pumps Hybrid Inverter 

200A Grid Passthrough

• Built-in to allow for cleaner, faster system installations. Eliminates the need to choose essential loads and route through a sub-panel
• Less wiring needed
• Fewer components simplify installation and reduce costs Residential Energy Storage Solutions 2x surge protection 

2X Surge Protection

• Inverter can handle sudden increases in power and supports a surge up to 24kW for up to 10 seconds
• Handles heavy motors and inductive loads, including well pumps, HVAC & compressors 

Dedicated Generator Passthrough

• Incorporate a permanent or temporary generator system at any time with minimal wiring and low complexity
• Get redundant back-up power with generator integration, the convenience of not having to physically start/stop generator and reduce fuel consumption Seamless Grid to Off-Grid Transfer Time 

5MS Transfer Time

• “No Glitch” seamless switching from grid to off-grid.
