SolaX Power Network Technology (Zhejiang) Co Ltd
The SolaX X1-VAST 5K is a 5 kW single-phase hybrid solar inverter (on-grid / off-grid / battery-ready) from SolaX Power. It integrates solar PV generation, battery storage, and grid/backup switching, enabling households to use solar energy, store surplus, and run loads during outages — all in one compact unit. It supports battery integration, smart-home energy management (self-consumption, backup, V2G/V2H), and is designed for flexible, scalable solar-plus-storage installations.
- Product Code:31003
- Model No.:X1-VAST-5K (AS4777-2 2020)
Hybrid Inverter + Battery-Ready Platform
- Works not just as a PV inverter but as a hybrid energy system controller — combining solar panels, battery storage and grid/inverter together.
- Supports dual battery ports and modular battery integration for expandability.
Flexible PV & Battery Input — High Oversizing for Better Yield
- Accepts generous solar input: supports up to ~ 200% PV oversizing.
- Four MPPT trackers (or for 5 kW model: 3 MPPT strings) for independent solar string tracking — helps maximize generation even if some panels are shaded or oriented differently.
- Low PV start-up voltage (≈ 50 V) — enables the inverter to begin harvesting solar power early in low-light conditions.
Backup / EPS & Off-Grid Capability
- Built-in EPS (Emergency Power Supply) mode — in case of grid outage, with battery connected, it can supply home loads.
- Fast switchover (< 10 ms) to backup power, with peak EPS output up to 2× rated power (for short duration, typically 10 s) — good for surge loads like motors, refrigerators, pumps etc.
Smart Home & Future-Ready Features (V2G/V2H, Energy Management, Expansion-Friendly)
- Ready for advanced use-cases like V2G (vehicle-to-grid) / V2H (vehicle-to-home), useful if you plan EV integration.
- Supports smart energy management: scheduling, time-of-use (TOU) settings, load prioritization, possibly virtual power plant (VPP) compatibility depending on region.
- Flexible wiring and dual-battery ports for easy expansion and clean installation.
