Telecom Hybrid Energy System

Provide integrated hybrid power solutions of PV, DG, electricity and battery storage in the area of no grid and unstable grid.

Connecting the world need modern communication services? Communication services need communication base station every where?

Communication base station need high quality power?


Does every where has the energy source to provide the power?

Good: Power capacity is large enough

Difficulty: Not everywhere there are power grids and substations; Power transmission line cost high; Electrical instability in remote areas.

Good:  Easy implementation

Difficulty: Maintenance cost high; Failure rate of DG is high; High cost of fuel consumption.

Good:   Renew , Clean, Every where

Difficulty: Solar power generation time is limited; The demand for space and land is proportional to the demand for power capacity; Initial investment cost is high.

Good:   Renew , clean, low lost of power generation

Difficulty:   Higher requirement for wind speed range;  Maintenance is difficult, maintenance cost high.

Only one is limitation, why not try hybrid?
Use one’s advantages, make up other’s deficiencies

(1) Solar-DG-battery Hybrid Solution

Application Scenario

Sites with long rainy days or serious unbalance of solar radiation in different seasons
Average solar radiation: ≥3 kWh/m2/day
Unavailable or unreliable grid power
Remote sites requiring high reliability power
Applicable to rebuilding of the traditional diesel generating sites, to reduce OPEX

TCO Comparison: Solar + DG hybrid solution VS Dual DG



 (2) From dual DG to DG + Battery (VRLA) Solution



(3) From dual DG to DG + Battery (Li-Fe) solution

Why using Lithium Ion Battery?

(4) Lithium Battery + VRLA Hybrid Solution

Advantage of lithium and VRLA battery hybrid solution

a) Charging and discharging can be customized as required
b) BMS can communicate with battery sharing controller, battery sharing controller can dynamically adjust the charging and discharging logic according to the data of lithium battery.
c) Lithium battery long life cycle and quick charge performance can be utilized well
d) Old VRLA battery also can be used as standby, saving investment
