EV4 Oregon’s Energy Transfer Merchant (ETM) is a complete system for charging EVs with renewable energy – a solar carport with battery storage and both AC and dual-mode DC chargers.
The ETM is a completely bolted system that covers two parking spaces. Its foundation is a concrete slab or an underground vault, depending upon the site. It is delivered to the job site as a kit and can be assembled in a few days.
The standard station is equipped with 15 solar modules (capacity 4 kW), one Level 2 charger, and one DC fast charger offering both CHAdeMO and CCS Combo connectors. The fast charger can be modified to handle other protocols including Tesla and future SAE standards.
The ETM’s structure protects the chargers from collisions, shelters drivers from the elements and provides security with lighting and surveillance. It collects rain water from the solar roof and filters it before delivery to landscaping. An LED sign can be installed on the canopy to display digital ads.
The battery system is grid-tied with a 3-wire single phase 120/240 VAC connection, and can provide power system back-up, grid support and load balancing services. The standard battery configuration is 50 kWh.
