Growatt 3kW Stackable Off-Grid Inverter | SPF 3000TL LVM-48P

48 V battery | 80 A MPPT | Pure-sine output | Parallel up to 6 units

Unlock clean, reliable power for cabins, RVs, tiny homes, or whole-house backup with the Growatt SPF 3000TL LVM-48P. This all-in-one off-grid inverter combines a high-frequency pure-sine inverter, an 80 A MPPT solar charge controller, and UPS-grade transfer switching in a single compact chassis—ready to stack for true 120/240 V split-phase or scalable to 18 kW in parallel.

Installer-approved advantages

• 3,000 W continuous / 6,000 W surge keeps essential loads running smoothly.
• Wide PV window (60-115 VDC, 4,500 W max) lets you string up to 145 VOC without combiner loss.
• High-current 80 A MPPT squeezes every watt from your array while safeguarding battery life.
• 48 V battery platform pairs effortlessly with today’s popular LiFePO4 rack batteries or sealed lead-acid banks.
• Stackable design: run two in split-phase for 120/240 V or parallel up to six (18 kW) for larger off-grid systems.
• UPS-grade transfer (<10 ms) protects sensitive electronics when switching between solar, battery, generator, or mains.
• Robust protections against overload, short-circuit, reverse polarity, and deep discharge.
• Smart connectivity: built-in CAN/RS-485 for BMS integration; add the optional Growatt WiFi dongle for cloud monitoring and remote firmware updates.
• Lightweight, transformer-less design simplifies wall mounting and reduces shipping costs.
