Since 2016, an off-grid photovoltaic (PV) ESS has been installed in Paiyun Lodge, the highest mountain lodge in Taiwan (as shown in Figure 1). In the system, solar panels provide intermittent energy generation, and the Li-ion battery ESS serves as an energy reservoir.
In 2016, an off-grid PV system with a Li-ion battery ESS was installed in Paiyun Lodge on Mt. Jade (the highest lodge in Taiwan). After operating for more than 7 years, the aging of the whole electric power system became a critical issue for its long-term usage.
Above all, this study gives engineers and researchers a fundamental understanding of a real case of the long-term usage of off-grid PV ESSs and engineering on high mountains. The simple cost model demonstrates that Li-ion batteries (instead of lead–acid batteries) are a better choice for long-term applications on high mountains.
Seamlessly switching between grid and off-grid modes, it allows for flexible configuration of photovoltaics, batteries, diesel generators, and loads. This versatility caters to multi-scenario
