Alencon Systems LLC has launched a new installation option (and acronym!) that will make its BOSS and SPOT lines of galvanically isolated DC:DC converters even more flexible. The FEED – or fused electrical disconnect – is installed with a SPOT or BOSS device in the factory that allows for a variety of interconnection and fusing options for Alencon’s DC:DC products.
What’s it do?
The FEED allows the user to specify the type of terminations on both the input and output of the device, including either screw terminals or PV connectors, appropriately rated disconnects and fuses as well as ground fault indication and fusing. The FEED has been specifically designed to simplify the deployment of Alencon devices across a broad variety of applications including repowering aged PV systems, DC coupling solar plus storage, EV charging and integration with fuel cells, among others.
“The FEED can easily be adapted for applications requiring uni-directional power flow using the SPOT platform or applications requiring bi-directional charge and discharge of batteries using the BOSS platform,” states Alencon Systems President Hanan Fishman.
Example: FEED + SPOT
For repowering, the FEED easily allows the SPOT to be installed after a plant’s existing combiner boxes, making tasks such as replacing failed 600-volt PV inverters much less labor intensive and thus far more cost effective.
The FEED can be used to place numerous SPOT units in parallel on the same DC bus either outdoors or inside the SPOT BOX.
Additionally, the FEED is great solution for building safe and reliable EV fast charging solutions. As the FEED offers both inputs and outputs from either screw terminals or PV connectors, it can easily be paired with virtually any string or central inverter topology.
FEED + BOSS
When paired with the BOSS – Alencon’s bi-directional DC:DC platform, the FEED is an excellent tool for use with battery energy storage applications. The FEED’s unique connector and fusing optionality is particularly helpful when DC coupling large scale battery energy storage with string inverters, a technique growing in popularity for commercial and industrial (C&I) and distributed generation (DG) projects ranging in size from 500 KW to 10 MW.
The FEED can be used when installing BOSS units inside a battery container and charging and discharging batteries at the rack level or when placing BOSS units in parallel on the same DC bus inside a battery container, outdoors or inside the BOSS BOX.
