The three-phase hybrid inverter Veichi VHT-15K-40-H with a rated capacity of 15 kW is engineered for backup systems requiring high-amperage (up to 40 A) high-voltage battery integration. Compatible with high-voltage (HV) lithium batteries, it features a swift transfer response under ≤10 ms to bypass grid failures. This model integrates 2 advanced MPPT trackers spanning 160-1000V, supporting up to 30 A per channel, making it ideal for bifacial solar panels. An IP65 protective casing supports solid outdoor wall mounting.
Typical Applications:
- Heavy duty backup power for luxurious estates combining EV chargers, pool heaters, split air systems, and continuous home needs.
- Constant power protection for private educational institutions, hotels, clinics, and tourist complexes.
- Commercial grid-interactive solar arrays for rural manufacturing nodes, large storage warehouses, and agribusinesses.
Critical Warning: Due to high peak capacity and continuous high-voltage loads, you MUST deploy 50 mm² copper DC cabling combined with a 250A DC fast-acting fuse. Program the correct BMS communication settings (CAN protocol code 08 or 15) immediately.
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
| Parameter | Veichi VH (VHS/VHT) | Deye SUN (LP/HP) | Solis RHI (5G) |
|---|
| Battery Voltage Class | 48V (1PH) / 135V–750V (3PH) | 48V / 160V–800V | 48V / 160V–600V |
| Transfer Time to Backup | ≤10 ms (UPS-class) | ≤10 ms (UPS-class) | ≤20 ms (EPS-class) |
| Enclosure Protection Rating | IP65 (Outdoor deployment) | IP65 (Outdoor deployment) | IP65 (Outdoor deployment) |
| Parallel Scalability limit | Up to 10 units in parallel | Up to 16 units in parallel | Up to 3 units (option card required) |
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.
