VHS-3.6K-30-H 3.6kW Hybrid Solar Inverter

The single-phase hybrid inverter Veichi VHS-3.6K-30-H with a rated capacity of 3.6 kW is designed for highly efficient backup power organization. Operates with high-voltage battery (HV) classes and supports adjustable charging and discharging currents up to 30 A. The ultra-fast transfer time of ≤10 ms prevents boilers and sensitive PC equipment from rebooting. This model integrates 2 MPPT trackers with a flexible range of 120-500V and built-in dry contacts for automatic backup generator starter controls. An IP65 dust and water protection enclosure enables stable inverter performance in demanding outdoor locations.

Typical Applications:

• Uninterrupted power supply for residential houses, deep water pumping stations, and HVAC heating controllers.
• Backup systems for office appliances, cash registers, communications, and emergency light systems.
• Distributed PV stations designed to maximize internal self-consumption and direct generated solar power.

Critical Warning: High-voltage DC lines mandate copper cables with a cross-section of 35-50 mm² and a dedicated 125A DC safety fuse. Setting up communication with the lithium battery requires precise BMS protocol matching (BMS code 02 or 05) on the LCD control panel.

Veichi VH Hybrid Solar Inverters — Premium Uninterrupted Power Supplies for Commercial & Home Backup

The Veichi VH hybrid solar inverter series (covering single-phase VHS 3–8 kW and three-phase VHT 4–20 kW models) represents VEICHI’s premium flagship range for off-grid power stability and smart energy storage. Engineered for tough industrial and heavy residential deployment, the VH range features a military-grade, rapid UPS-level transfer time to backup battery storage (≤10 ms), keeping high-sensitivity IT servers, medical gear, and household appliances fully online during grid utility blackouts. The entire series is enclosed in a rugged, cast aluminum alloy frame rated IP65, allowing trouble-free indoor or outdoor wall mounting exposed to weather.

Typical Applications for Veichi VH Series

• Seamless Home & Office Backup: Instant UPS-grade transfer ≤10 ms shields server rooms, networking terminals, and heating pumps from voltage spikes and blackouts.
• Off-Grid Business Microgrids with Diesel Support: Utilizing the onboard dry contact relay terminal, the VH controller automatically commands generator startup during low battery states, dynamically mixing PV solar with diesel energy.
• High-Voltage Commercial Battery Banks (for 3-Phase VHT): Direct compatibility with high-voltage Lithium battery strings (135V–750V) boosts overall conversion efficiency up to 98.8%, minimizing cable thermal stress and B2B line losses.

What Differentiates Veichi VH from Competitors

The standout engineering differentiator of the Veichi VH range is its dedicated, programmable **Smart Load / Aux port**. This allows designers to wire a secondary low-priority load line (such as domestic water boilers or EV chargers) configured to activate only during peak solar PV surplus, preserving battery state of charge.

When Veichi VH is NOT Suitable

• For low-power off-grid sites where investing in high-voltage industrial gear is not financially justified — select the compact single-phase Veichi SI range.
• If your industrial solar array calls for parallel integration of more than 10 units — select the heavy commercial three-phase Deye SUN series supporting up to 16 parallel units.

Our Engineering Integration Experience

The Veichi VH series displays outstanding BMS handshake compatibility with modern Lithium battery banks. To initiate reliable CAN/RS485 data connection, select battery type LIB in the inverter programming keypad and specify the correct protocol ID address (such as PACE or Pylontech). When integrating Felicity or Must battery modules, we highly advise checking the pinout of the data link cable, as stock patch cords often carry mismatched contact layouts. Premium compatible batteries are available in our lithium solar batteries catalog.
