In partnership with Ampt, a DC optimizer firm targeted on large-scale PV methods, JONSOL, the German producer of photovoltaic (PV) modules, has develop into the primary module and system provider worldwide to supply an optimized PV plus DC-coupled energy storage resolution. JONSOL has been working with Ampt to develop a much-needed string inverter-based DC-coupled PV+storage resolution that delivers value financial savings by way of flexibility, scalability and ease.
The pre-engineered JONSOL resolution is comprised of JONSOL modules, Ampt string optimizers and a bidirectional battery inverter to offer a versatile PV+storage design block that scales from small microgrids to bigger industrial-sized PV methods that may be deployed on rooftops, within the area or floating on water.
The JONSOL resolution could be operated in parallel on the DC facet to attach a number of bidirectional inverters to a single high-capacity battery. The resolution is appropriate with lithium-ion batteries and different commercially accessible battery varieties to offer versatile storage capability and durations to satisfy particular utility wants like peak shaving or ancillary companies. The inverters can be related in parallel on the AC facet in limitless numbers for a variety of system sizes.
Ampt string optimizers are DC/DC converters that carry out most power level monitoring (MPPT) on every string of PV modules. With Ampt, the PV array is related by way of the optimizers and on to the DC bus between the battery system and inverter. Ampt optimizers additionally embody V-match expertise, permitting the optimizers to ship full accessible power from the array whereas routinely matching the DC bus voltage because it modifications with the battery state of cost. In addition, Ampt optimizers seize the energy that might in any other case be misplaced to extend the lifetime manufacturing of the system.
By pairing the bidirectional battery inverter and Ampt power administration parts collectively, the JONSOL PV plus DC-coupled energy storage resolution eliminates the necessity for a devoted PV inverter to avoid wasting on gear prices and enhance the system’s round-trip effectivity. The string inverter-based design utilizing a battery inverter additionally achieves larger uptime to enhance lifetime efficiency. It has fewer conversion losses, higher reactivity, and sooner response instances in comparison with different methods in the marketplace. When mixed with JONSOL modules, prospects profit from a completely appropriate and built-in resolution.
