As the leading vertically integrated manufacturer of lithium iron phosphate battery systems, Pylontech has provided various battery solutions for nearly all kinds of Energy Storage System (ESS) applications. Thanks to their self-developed core technology in cells, and battery management system, Pylontech has delivered more than 3.0GWh of batteries serving more than 200,000 users.
The Pylontech US3000C is an energy storage system representative of the latest generation. This lithium (LiFePo4) battery is designed to fulfill the high demands that are required of an Energy Storage System in Canada, which includes high safety levels and a long service life even when the battery is regularly deeply discharged, thanks to its integrated Battery Management System (BMS).

Grid-Tied Battery Backup Application
The Pylontech US3000C is a great add-on for a grid-tied solar system, new and existing. In a regular Net Metering system, excess power produced by the solar system is 'sold' to the Hydro company for credit against the power bill, typically covering the cost of dark winters and night electricity usage. Adding a energy storage system to a grid-tied solar system is typically used for home backup in case of a grid power-outage. For further details, please have a look at Frankensolar's Backup Packages. Typical batteries chemistries for backup systems are traditional lead acid AGM (sealed, maintenance free) or nowadays with the cost reductions in Lithium batteries Lithium-Iron-Phosphate LFP, like the Pylontech US3000C module. The main advantage of a Lithium battery system in a backup installation is not the cycle life of the battery, it is mainly the long life expectancy in a float application and the high energy density of the system. It is significanly more compact and can be scaled better in smaller utility rooms compared to traditional AGM lead acid battery racks/shelves.
Off-Grid, Cottage or Tiny House Application
In comparison to a grid tied system, Off-Grid systems need to provide all their power demands out of the solar and battery system with a (gas) generator as a typical backup source. This results in a very different load and cycle application compared to a battery backup system. For Off-Grid, high peak power capabilities of the battery system is required to allow the connected hybrid inverter to supply temporary peak power to loads like pumps and compressors of fridges and freezers when these loads start (inrush current). Lithium battery technology is ideal to provide that peak in a very compact design. On the other hand, in an Off-Grid scenario the battery system is cycled on a daily basis making the life expectancy of the battery investment one of the most important criteria of the actual cost per kWh consumption.
Lithium Ion chemistries have, in most cases, much higher cycle life expectancy compared to traditional lead battery chemistries. The following diagram shows a general comparison between the average depth of discharge of a battery to the available number of cycles of the battery.
