Products Description
what is Solis S6 5-8KW Three phase Inverter?

At Mutian Solar Systems, we create energy solutions that redefine boundaries. The collaboration with Solis to incorporate the Solis S6 5-8KW Three phase Inverter Module into our modular solar-storage systems presents a sea change in energy for communities and households - how they see it, use it, and the registers in which it is stewarded. This is more than just a product collaboration; it's a reimagining of the energy ecosystem as a dynamic, adaptive network capable of fostering resilience, intelligence, and synchronization with nature.
cases
Mutian's S6-EH2P modular flexibility brings brand-new levels of scalability and Mutian's vision of scalable energy independence through decentralization. In situations where grid reliability is not an option these systems take advantage of this inverter allowing access to solar energy for whole villages, jointly creating for this collective reliable, resilient, renewable power for schools, health facilities, and small businesses that are educating, health care providing, and putting small businesses in place to ensure continuing economic resilience.
For instance, one Mutian project in Southeast Asia incorporated clustered S6-EH2P inverters that powered a microgrid for more than 500 households. With the addition of both back up generators and smart load controllers, they reached 98% energy autonomy meaning they nearly didn't rely on these expensive diesel imports, as well as negated numerous carbon emissions.

Features
• Supports PV input up to 160% of the inverter's rated DC power, maximising solar utilisation
• Supports up to 21A PV input current, compatible with the future higher-power PV module
• 200% overload for 10s in off-grid mode, ensuring stable startup of motors, water pumps and air conditioners
• Seamless on/off-grid switching in under 10ms, guaranteeing uninterrupted power supply
• Support split-phase unbalanced output, each phase supports output max. 50% rated inverter power
• More battery options, compatible with any battery (between 40V-60V)
• Multiple methods of generator connection and auto control, enabling flexible local deployment
• Support max 6 pcs in parallel, expanding system capacity
• Smart Load management, extending backup time for critical loads
• Customizable battery backup level for uninterrupted power
• PV only off grid mode, to reduce the initial investment cost
• 7-inch industrial-grade touchscreen, providing a larger, user-friendly interface for local operation
• Supports existing PV grid-tie power connection for export control and off-grid use
• Ingress protection IP66, adapting to harsh ambient conditions
Conclusion: Energy as a Human Right
Together we are not only selling inverters, we are empowering generations of people to take back their energy story.
