Schneider Electric Solar, through their website announced the launch of a new high-power Solar Charge Controller: MPPT 100 600 Solar Charge Controller. The Conext MPPT 100 600 Solar Charge Controller provides 25% more charging power as compared to MPPT 80 600 charge controller.

The MPPT 100 is perfect for homeowners, it allows them to optimize battery charging from solar and maximize energy resiliency, in the pursuit of whole-home backup. It is also suitable for prolonged blackouts. When a battery is fully discharged during night, and the battery inverter shuts down, the MPPT 100 charge controller allows the system to recover when PV returns.

The new solar charge controller is compatible with Schneider Electric’s storage inverters: Conext XW and SW, for a complete solar & storage solution. Just like Schneider Electric’s MPPT 60 and MPPT 80, the MPPT 100 is also compatible with the MPPT Disconnect RS accessory for rapid shutdown compliance, fire safety, and arc fault detection.

With the allowance for over-sized arrays, the MPPT 100 allows for 7 kilowatt (kW) solar power arrays. It is ideal for residential grid-tied self-supply and off-grid systems and is scalable for larger installations. For installers, the 600 V MPPT 100 offers faster installations and lower balance of system costs.

The product is designed to operate at 600 V, including the temperature correction factor, which drives a reduction in balance-of-system costs. With 2 PV string per charge controller, MPPT 100 600 offers 50% less wiring than low voltage charge controllers. The charge control is carried out by a three-stage set-up in which bulk, absorption and float methods are used, in addition to the option of manual equalization.

According to the manufacturer, in terms of battery voltage, Schneider’s new device can handle 24 and 48 V products. The battery operation voltage range was announced as 16-67 Vdc. The higher the battery voltage, the better the power conversion efficiency, with 95% efficiency measured for 48 V battery technologies and 92% for 24 V devices.

Equipped with a wide operating voltage range – 195-550 V for the PV system – and a similarly open MPPT voltage range, of 195-510 Vdc, the manufacturer says its product offers greater flexibility in string sizing than rivals. The MPPT algorithm is also said to be shade tolerant and ‘fast sweeping,’ according to Schneider, further improving the energy harvest.
