Telecom & monitoring site wind turbine

A base station needs 200–600 W, 24 hours a day, in places where the grid is either absent or dies every second week. Wind plus solar plus a battery is now cheaper than the diesel generator it replaces — and it does not need a fuel delivery.

Telecom sites are the ideal small-wind load: constant, small, and tolerant of voltage sag. A 1 kW turbine with 1 kWp of PV and a 48 V / 200 Ah battery keeps a 300 W BTS load running indefinitely in a 5 m/s site, with five days of autonomy for the calm, overcast week.

The engineering challenge is not the turbine, it is the enclosure: -30 °C in winter, +55 °C inside a cabinet in summer, salt spray on the coast, and lightning on every ridge. Our telecom kit ships with a NEMA 4X enclosure, a DIN-rail controller, and surge arrestors on both the DC and the AC side.

Typical load profile

Load	Power	Hours/day	Daily energy
4G/5G BTS (macro, low load)	350 W	24 h	8.4 kWh
Microwave backhaul	80 W	24 h	1.9 kWh
CCTV camera + IR	25 W	24 h	0.6 kWh
Sensor / RTU package	15 W	24 h	0.36 kWh
Cabinet cooling fan	40 W	8 h	0.32 kWh

Recommended configuration

Recommended model: WT-1000H (1 kW) on a 12 m tower
Hybrid: 1 kWp PV, 48 V 200 Ah LFP
Autonomy: 5 days at 300 W average
Monitoring: RS485 + 4G gateway, SMS alarms
Installed cost: USD 7,500 – 11,000
Diesel displaced: About 3,500 litres/year per site

Five days of autonomy is the design point

Operators size for the worst calm, cloudy stretch, not the average. Five days at 300 W is 36 kWh of usable storage — which is why the battery, not the turbine, dominates the cost.

Remote alarms save truck rolls

The controller reports rotor speed, DC voltage, battery state of charge and dump-load temperature. A truck roll to a mountain site costs more than the monitoring hardware.

Wind beats solar in the mountains and on the coast

PV output in a mountain valley drops by half in winter; coastal sites have strong night breezes. That is exactly where hybrid wind-solar pays back fastest.

Frequently asked questions

Can I power a 5G base station with wind?

A low-load 5G macro site draws 350–800 W continuously, which a 1–2 kW turbine with 2 kWp PV and a 48 V battery can carry off-grid. High-load MIMO sites at 1.5 kW+ are usually better served by a 3–5 kW machine.

What happens in a typhoon or a -30 °C night?

The turbine survives to 59.5 m/s with the rotor locked; the battery heater keeps the LFP pack above -5 °C; the controller derates charging below 0 °C. All three behaviours are configurable in the commissioning menu.

How often does it need maintenance?

One visit a year: blade inspection, bolt torque, filter cleaning, firmware and battery health check. Mean time between failures on the generator is over 40,000 hours in field data from our installed sites.
