Solar Hybrid Telecom Power System 48V for Off-Grid & Weak-Grid BTS — Outdoor Cabinet with 12.8kW PV Charger, Grid + Solar Operation

Cut site energy cost and improve network availability with this solar-ready outdoor telecom power cabinet. The FP2 48V hybrid system powers BTS and transmission loads from mains (3-phase 400V+N) and photovoltaic input simultaneously, with up to 12.8kW of solar charging capacity managed by Flatpack2 48/3200 HE solar charger modules. This standard supply includes 2 solar charger modules (6.4kW PV installed) and 5 high-efficiency rectifier modules (15kW AC installed), all hot-swappable inside one air-conditioned Type 3 outdoor enclosure.

For sites where grid quality is poor or diesel is the only alternative, the photovoltaic input reduces grid/diesel dependence and extends site autonomy when combined with the integrated Li-ion battery shelves. The Smartpack2 controller handles hybrid power priority, battery charging, low-voltage disconnection and alarm reporting in one platform, so the site runs intelligently — grid and solar working together instead of competing.

Key features:

• Grid + solar hybrid DC power in a single cabinet — no separate PV combiner/charger boxes to integrate
• Expandable PV capacity: 4 slots × 3.2kW solar chargers = up to 12.8kW solar input
• 48V DC air-conditioned Type 3 outdoor cabinet for hot, dusty and desert environments
• Li-ion battery ready: 4× 3U battery shelves supplied, up to 6 shelves supported
• Full protection set: AC SPD (20/40kA), PV panel with DC SPD, 6× 100A battery breakers, LVBD 600A / LVLD 300A
• Remote monitoring & alarm management via Smartpack2 Touch + Basic + I/O monitor
• Factory acceptance tested before shipment; 12-month warranty

 Application Scope

• Telecom BTS/NodeB sites in off-grid, weak-grid or unstable-grid regions
• Solar hybrid sites for tower companies aiming to cut grid OPEX and diesel consumption
• Desert, rural, island and high-temperature outdoor installations
• Green/energy-saving telecom network rollouts (grid + PV + battery hybrid architecture)
• Sites requiring high availability with limited genset runtime
• DC power for transmission nodes, microwave and broadband backhaul equipment
