Technical FAQs 4

Can off-grid PV ESSs be used on high mountains?

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.

Is there an off-grid PV system on Mt Jade?

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.

Which battery system is best for the high mountains?

It is obvious that for the long-term usage of the battery system in the high mountains (or a region where the extra moving cost is very high), the Li-ion battery system is a more economical and environmentally friendly choice.

How do hybrid solar inverters work?

The power of all PV arrays directly passes through the hybrid solar inverters and then goes to the Li-ion battery ESS. By replacing the hybrid solar inverter with a new version, the maintenance problem of the system can be solved, and the system can be prevented from shutting down for a long time.
