Fleet vehicles charged by enerpak solar charge maximizing controllers

ENERPAK’s Level 2 and Level 3 charge controllers are powered by our patented Solar Charge Maximizer Systems.

The High Voltage DC Photovoltaic Power Controlled by the ENERPAK's Patented SCMC System to Charge the EV Batteries Directly without the Power Transmission Loss in the Grid. 

There is no transformers, nor inverters, nor converters are required to pass the PV energy from the solar arrays to the EV batteries. The PV power is harvested and used for Level 3 DC charging at the location where the fleet vehicles are parked.

  • ENERPAK PV4EV Lever 1 & Level 2 EV Charging System Features

    • The 24VCN or 48VCN Solar Charge Maximizer System supplies 120VAC single phase or 240 VAC split phase power to the regular level 1 or level 2  EV chargers to charge the EVs. 

    • The dry contact in the solar charge maximizer passes high current continuously to power a solar inverter for VAC power supply.

    • The EV chargers are generally built with J1772 plug which are widely used in North America, and it is also compatible with SAE CCS1 combo standard. (A adaptor may be required for other types of the vehicles.)

    • The components in the Level 2 of PV4EV system is essentially required for upgrading to Level 3 DC charging.

  • ENERPAK PV4EV Level 3 (or DC) Charging System Features

    • The DC power from solar panels is passed to EV directly without the need for AC transformers, and rectifiers.

    • The power from solar array is 100% pure DC without fluctuation to smoothly charge the EVs for maximum battery protection.

    • The maximum current from a solar array is limited by the solar panels, and the total capacity is sized according to the maximum power that EV can support.

    • We use SAE CCS1 plug for DC and Level 2 AC charging;

    • Our DC charging controller can be programmed according to IEC 61851-23, IEC 15118 or DIN SPEC 70121 standards to match most of the fleet trucks in North America.

ENERPAK's Patented Dual Voltage (48V & 400V) Master Solar Charge Maximizer System for Level 2 AC and Level 3 DC Electric Vehicles Charging 

Depending on the available space for solar panels mounting, and if it is roof-mount system or rack-mount systems or parking canopy system, the solar charge maximizing controller system for fleet EVs charging can be designed and installed for any fleet EVs in almost every commercial building and every parking lot. 

  1. All the fleet EVs can be charged during the day when the sun is up, and whenever they are parked at the business facilities.

  2. Level 2 chargers are gentle to the fleet EVs to maximize the EV battery service life, after the ENERPAK's unique high voltage solar charge maximizer (400VCN80A) charges the EV to 80% of its battery capacity. The EV batteries can always be charged to the full capacity through the solar inverter with 240vac power supply for level 2 charging in the same system.

  3. Your fleet EV numbers are no longer limited by your building's total electrical power supply capacity.

  4. There is no grid-tie approval nor electrical power supply upgrade required, nor any stress on the existing power grid.

  5. The PV4EV systems are immune to power supply interruption due to the extreme weather conditions.

  6. You can provide endless power for EV charging by turning the building roof area and parking lot into natural energy harvesting resource, and save the spending on fleet gas cards as well as the earth.

  7. The remaining PV power may be used for building domestic water preheating tanks heating, when the EVs are all fully charged.
