Which panels are compatible?
Rigid panels up to 8 kWp or SuperLight 410 W for mobile and emergency setups.
How long does the battery last?
Barrel 5.0 uses LiFePOâ‚„ cells (>6,000 cycles). The Graphene version goes up to 500,000 cycles with 100% DoD.
Is installation complex?
No. The systems are pre‑cabled. Connect the panels, power on, and start producing.
Do you offer training and support?
Yes. Through the Solar of Things platform and the Help Desk (AI, Technical, Engineering).
Do you ship internationally?
