VHS-5K-L01-K Hybrid inverter Silent 5kW 1phase (battery 48V)

The single-phase hybrid inverter Veichi VHS-5K-L01-K with a rated capacity of 5 kW is purposefully engineered to modernize solar plants utilizing standard low-voltage 48V battery (LiFePO4 or Lead-Acid) banks. The device supports an impressive charging and discharging current of up to 120 A, ensuring fast power transfer from the accumulators. An ultra-fast transfer time of ≤10 ms to backup power keeps your household shielded from utility blackouts. Equipped with 2 high-efficiency MPPT trackers (120-500V range) and integrated generator dry contacts. Its robust IP65 enclosure guarantees flawless performance in harsh outdoor settings.

Typical Applications:

• Upgrading existing solar networks to modern hybrid topologies while preserving active 48V low-voltage battery banks.
• Emergency and backup power supply for family cottages, medium properties, and specialized retail businesses.
• Clean backup power for deep well pumps, automated watering lines, and essential home appliances.

Critical Warning: Due to the high peak current limits of up to 120A on 48V batteries, you MUST use heavy 35-50 mm² copper DC cables and a certified 150A fast-acting DC fuse on the battery terminal. Match the CAN/RS485 interface to your low-voltage battery BMS protocol.

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.
