The Solis S6-EH3P(30-50)K-H Series: Commercial Usecases for 30kW, 40kW, and 50kW Inverters

The Solis S6-EH3P(30-50)K-H series consists of three-phase, high-voltage commercial hybrid energy storage inverters with power outputs ranging from 30 kW to 50 kW. Engineered by Ginlong Solis, this series bridges the gap between commercial rooftop solar generation and high-capacity battery storage systems.

This is a high-voltage, commercial-scale battery inverter, built for factories, warehouses, and C&I sites where the goal isn't just backup power it's actively managing electricity costs and battery economics at scale.

Key Features In Series: 30-50kW

High-Voltage Battery, Not Low-Voltage

Where the residential and small three-phase hybrids in this series run batteries at 40-60 V, the S6-EH3P(30-50)K-H operates a 150-800 V battery voltage range, built specifically for high-voltage lithium battery banks. That's a fundamentally different battery architecture the kind used in commercial energy storage rather than home battery packs and it's designed with two independent battery inputs, each capable of 33-35 kW of charge/discharge power.

Peak Shaving Is Built In, Not Bolted On

This is the first model in the series with dedicated peak shaving support, available in both "self-use" and "generator" modes. For a commercial site on time-of-day tariffs, that means the inverter can be configured to draw from the battery during expensive peak-demand windows and recharge during cheaper off-peak hours a direct line item on the electricity bill, not just a backup feature.

Battery Healing and Remote Monitoring

Large battery banks degrade unevenly across cells over years of cycling. The S6-EH3P(30-50)K-H includes real-time battery monitoring, remote upgrade capability, and a battery healing function aimed at extending pack life relevant at this scale where a battery bank represents a serious capital cost, not a $2,000 home battery that gets swapped out.

The Numbers That Matter for Sizing

Solar Input

• Recommended max. PV array size: 60 kW (30K) / 80 kW (40K) / 100 kW (50K)

• Max. input voltage: 1000 V, MPPT range 150-850 V

• Max. input current per string: 20 A, sized for high-power PV modules from any manufacturer

• Supports up to a 200% DC/AC ratio, meaning the array can be oversized relative to inverter capacity to keep the battery charging fully even on shorter winter days

Battery Side

• Battery type: Li-ion only (this model doesn't support lead-acid)

• Voltage range: 150-800 V

• Max. charge/discharge power: 33 kW / 44 kW / 55 kW across the 30K/40K/50K models

• Charging/discharging current of 140 A (70 A + 70 A across two inputs), sized for 280 Ah cells at standard 0.5C a spec aimed squarely at the commercial LFP battery packs common in Indian C&I installations today

Grid, Backup, and Generator

• Rated output power: 30 kW / 40 kW / 50 kW, matching each model name

• Backup switch time: under 10 ms

• Overload capability: 160% for 2 seconds on backup enough to absorb a motor or compressor startup surge without tripping

• Generator input rated to match the inverter's full output, so a diesel or gas generator can carry the full load once battery and grid options are exhausted

Efficiency and Build

• Max. efficiency: 97.8%, EU efficiency 97.4%

• Battery-to-AC discharge efficiency: 97.5%; PV-to-battery charge efficiency: 98.5%

• IP66 rated, operating range of -25°C to +60°C, max. altitude of 4000 m

• Night-time self-consumption of under 35 W a small but real efficiency detail for sites running the inverter continuously

• Full protection suite: anti-islanding, output over-current, insulation resistance monitoring, short-circuit, integrated DC switch, DC reverse-polarity, and DC/AC Type II surge protection

Hybrid Series : Residential To C&I

Commercial Use Cases Of This Model

• Factories and warehouses on time-of-day electricity tariffs that want the battery actively working against peak demand charges, not just sitting idle for outages.

• C&I sites already running high-voltage lithium battery banks, where a low-voltage hybrid inverter simply isn't compatible with the battery architecture.

• Facilities with generators as a fallback, where the inverter needs to coordinate grid, battery, and generator inputs without manual switching.
