SUMT Inverters: ECO-HV, MAX, NM-ECO Series – Power Options & Core Advantages
SUMT’s three inverter series—ECO-HV, MAX, and NM-ECO—are engineered to address diverse energy needs. ECO-HV excels in large-scale parallel operations, MAX delivers high efficiency for commercial/industrial use with dual PV inputs, and NM-ECO offers flexible dual-load management for residential and small-scale applications. This guide details their power options, product features, core advantages, and application scenarios to help users make informed choices.

ECO-HV Series: Parallel Expansion Expert for Large-Scale Projects
Power Options
- ECO-HV-3012: 3000W
- ECO-HV-3048: 3000W
- ECO-HV-4524: 4500W
- ECO-HV-5548: 6000W
- ECO-HV-6548: 6500W
Product Features
- Adjustable output voltage (100-240VAC) for compatibility with US and EU grid standards, eliminating the need for modifications in overseas projects.
- Wide PV input range (60-490VDC) suits high-voltage solar systems, reducing transmission loss by 15% compared to low-voltage setups, with 97% PV-to-AC conversion efficiency.
- Supports EQ activation for lead-acid batteries and charging wake-up for lithium batteries, ensuring compatibility with mainstream energy storage batteries.
- Built-in automatic temperature regulation with power derating at high temperatures, operating stably between -10°C and 50°C to adapt to global climates.
Core Advantages
Flexible Power Systems via Multi-Unit Collaboration: 2 units in parallel enable split-phase output (ideal for 120V/240V mixed power needs in North America); 3 units form a three-phase 380V system to directly power industrial motors and pumps; up to 12 units can be paralleled for linear power scaling, eliminating the dilemma of initial overcapacity or future insufficiency in large projects.
Application Scenarios
- Overseas industrial parks and large commercial complexes
- Multinational corporate factories (requiring three-phase 380V power)
- Large new energy microgrids (e.g., independent power systems for islands, mining areas)
- European and American community solar storage projects (compatible with 100-240V grids)
MAX Series: Dual PV Input Powerhouse for Commercial & Industrial Stability
Power Options
- MAX-8.2KW: 8200W
- MAX-10.2KW: 10200W
Product Features
- Maximum solar charging current of 160A, allowing 100kWh+ batteries to reach 80% charge in 2 hours, meeting 8-hour night shift energy needs for factories.
- Dual-output design isolates critical loads (e.g., production line PLC systems) from general loads (e.g., office lighting), prioritizing core equipment during power outages.
- Seamless grid-tie/off-grid switching (<10ms), below the power-off tolerance threshold of precision devices like computers and servers, preventing data loss or equipment damage.
- Wide frequency range (45-65Hz) ensures stable operation in regions with unstable grids, reducing downtime.
Core Advantages
Dual PV Inputs Overcome Lighting Limitations: 5400W+5400W dual independent inputs can connect to east/west-facing roof panels or fixed+tracking arrays, increasing daily power generation by 12%-18% compared to single-input systems—ideal for commercial buildings with complex roof orientations or variable light angles.
Application Scenarios
- Traditional factories and shopping malls
- Data center backup power (needing dual-path supply)
- Cold storage warehouses (isolating refrigeration units from lighting to prevent cargo spoilage during outages)
- Large agricultural greenhouses (dual-path connection to panels in different areas, ensuring uninterrupted irrigation)
NM-ECO Series: Dual-Load Specialist for Homes & Small Businesses
Power Options
- NM-ECO-4.2KW PLUS: 4200W
- NM-ECO-6.2KW PLUS: 6200W
Product Features
- 98% maximum conversion efficiency, generating 5%-8% more power in low-light conditions (e.g., rainy days) and adding ~300kWh annually per household.
- WiFi/GPRS connectivity with mobile app control, supporting "peak-valley charging" and "PV priority" modes (e.g., charging from the grid at night 低谷电价 and using stored energy during daytime peaks, saving households $40-$70 annually).
- Dustproof filter and sealed design for long-term operation in dusty northern rural areas or greasy restaurant kitchens, reducing maintenance frequency.
- Supports battery-free grid-tie operation, allowing users to install PV panels first and add batteries later (3-5 years), lowering initial investment barriers.
Core Advantages
Dual-Load Management Enhances Power Security: Separates primary loads (e.g., refrigerators, air conditioners) from secondary loads (e.g., TVs, lights). When battery levels drop below 20%, secondary loads are automatically cut off to protect critical devices—preventing food spoilage in home refrigerators or fresh goods loss in small stores (maximum secondary load power: 2067W, covering most common devices).
Application Scenarios
- Residential homes and convenience stores
- Homestays (isolating guest room AC from public lighting to ensure basic power during outages)
- Small farms (powering irrigation pumps as primary loads and monitoring systems as secondary loads)
- Community convenience stores (separating refrigerators from cash registers, prioritizing cold chain when batteries are low)
