Shining light on a new way to power refrigeration units
The sun is one of the most important sources of energy for all life on earth. It can also be a source of power for your all-important refrigerated transportation services. To harness that power, eNow’s proprietary, lightweight, flexible, 0.125-inch solar panels – including an ETFE (Teflon) outer layer – capture sunlight and convert it to direct current (DC) electricity. The DC electricity goes to eNow’s smart maximum power point tracking charge controller, which maximizes the power output of the photovoltaic panels and then sends the power to an auxiliary load (e.g., HVAC, lift gate, safety lighting, refrigeration) or battery system.
In refrigeration applications, the demand for battery power to keep the refrigeration unit running is at a premium. Smaller alternators and anti-idling laws can leave your TRU starved for power, resulting in spoiled goods. When the sun rises, eNow’s charge controller does a bulk charge to replenish the batteries. Once the charger detects the batteries are fully charged, it goes into a trickle charge (or float) mode. It will continually trickle charge the batteries during daylight hours, even on cloudy days, and then contributes directly to bulk charging the batteries to replace the energy used as the refrigeration unit works to maintain a stable temperature during deliveries. This all happens automatically with no driver action required and whether the engine is on or off.
