FAQ
The NV (Normal Voltage) models connect to standard 480V AC three-phase commercial utility grids, while the LV (Low Voltage, e.g., S6-EH3P30K03-LV) models cater to 208V/240V AC three-phase electrical services. Both variants retain identical core software features, including dual high-voltage battery ports and rapid shutdown support. Selecting between NV and LV depends on the utility service voltage available at your facility transformer.
This series utilizes a high-voltage battery architecture (typically ranging from 150V to 800V DC) rather than low-voltage 48V systems. It features two independently controlled high-voltage battery input ports supporting combined charge/discharge currents up to 168A (84A per port). This dual-port architecture allows installers to configure separate battery strings or mix module capacities, speeding up energy replenishment while minimizing DC wiring power losses.
The inverter series supports up to 100 kW DC of solar input, accommodating up to 166% to 200% DC-to-AC oversizing ratios to maximize daily production. Equipped with up to 4 independent MPPTs handling string currents up to 21A, the units easily pair with modern large-format, high-power solar panels without suffering performance clipping during peak sunlight hours.
Upon utility grid failure, the inverter automatically isolates from the grid and transfers critical electrical loads to backup power in under 10 milliseconds. This rapid UPS-level transition prevents sensitive servers, IT infrastructure, and commercial machinery from rebooting or shutting down. The backup port can also handle short-duration surges up to 160% of rated capacity to start heavy equipment motors.
The system includes a dedicated smart load and generator connection port with Automatic Generator Start (AGS) control logic. During extended power outages with low solar output, the inverter automatically commands a standby generator to start. The generator powers connected facility loads directly while simultaneously recharging the high-voltage battery bank, delivering uninterrupted multi-day power resilience.
Yes, up to 10 units can be paralleled on a single system bus, enabling total power scalability up to 600 kW of continuous continuous AC output. The integrated master-slave communication architecture ensures synchronized three-phase output, balanced battery bank charging, and uniform load distribution across all paralleled nodes without requiring complex external third-party control hardware.
The inverter features time-of-use (TOU) and peak shaving modes operating in both self-use and generator configurations. Facility managers can program the inverter to discharge stored battery energy during expensive peak utility rate hours to reduce peak demand charges. Intelligent load prioritization also allows non-critical electrical loads to be shed automatically when reserving emergency battery backup power.
Engineered to strictly meet North American electrical safety codes, the inverter features an integrated SunSpec-certified rapid shutdown transmitter for NEC 690.12 compliance. It incorporates Arc-Fault Circuit Interrupter (AFCI) protection to mitigate electrical fire risks, ground fault protection, and DC reverse polarity safeguards, while fully complying with UL 1741 SB and IEEE 1547-2018 grid interconnection standards.
Carrying a NEMA 4X / IP66 ingress protection rating, the inverter's internal electronics are sealed against dust, heavy rain, blowing snow, and corrosive air. It operates across a broad temperature range of -13°F to 140°F (-25°C to 60°C) utilizing intelligent fan-forced cooling, allowing direct outdoor wall or equipment-rack mounting without needing expensive indoor electrical room construction.
The unit incorporates a 7-inch industrial display and standard communication hardware, including RS485, dual CAN ports, Ethernet, and optional Wi-Fi or Cellular modules. Operators monitor system telemetry, battery state-of-charge (SOC), and peak shaving schedules remotely through the SolisCloud web platform or mobile app, which also supports over-the-air (OTA) firmware updates to streamline long-term maintenance.
The only difference between the two models is the brand of the integrated Module-Level Rapid Shutdown (MLRSD) transmitter included inside the inverter.
- Solis S6-EH3P(30-60)K-NV-YD-H-US-RSS: This variant includes an integrated Tigo RSS (Rapid Shutdown System) transmitter. This transmitter is designed specifically to pair with Tigo-brand rapid shutdown receivers (such as the TS4-A-F and TS4-A-2F models).
- Solis S6-EH3P(30-60)K-NV-YD-H-US-APST: This variant includes an integrated APS (APsmart) MLRSD transmitter. It is used when building a system paired with APS-brand rapid shutdown receivers.
Both models maintain identical core technical specifications for power output, high-voltage battery compatibility, and grid interconnection. The suffix strictly dictates which rapid shutdown ecosystem the inverter supports out of the box.
