Sophisticated 60A 12/24/48V MPPT charge controllers with 180VDC maximum input voltage

All Steca solar charge controllers have an integrated temperature sensor that makes them capable of adjusting the charging to suit temperature conditions. However, if the battery is installed in a different room to the controller a n additional external temperature sensor should be used.

• Rating 1000V, 40 A (with 4 mm² cable)
• Compatable with conductors from 2.5 to 6 mm²
• Temperature rating: up to 85 °C ambient temperature

Sunny Island Accessories for older model Sunny Island inverters

An automatic transfer switch, suitable for the SMA 'Flexible Storage System' which allows operation to continue in case of main power blackouts. Contactors ensure compliant earth switching.

Double pole circuit breakers. These protect the DC cables between batteries and inverters against overcurrent and short-circuit and allow easy isolation for installation or maintenance of the inverters.

Allows disconnection of loads in event of low battery state of charge. Controlled by signal from programmable relays inside the Sunny Island inverter.

Used to measure DC current when there are loads or charge sources directly connected to the battery. Allows the Sunny Island inverters to include these in it's state of charge calculations and ensure accurate battery charging.

Used with the Master inverter of each cluster with lead acid batteries to ensure correct battery charging.

This AC distribution cabinet acts as the hub in large off-grid systems and is used with Sunny Island X inverters, connecting and managing all system components.

This provides means of monitoring solar insolation, temperature and wind speed as long term data monitoring and checking performance of a wind or solar system. Includes solar cell with +/- 8% accuracy. Optional higher accuracy cells, wind anemometer, and temperature sensors. Easy to connect via RS485 or Bluetooth to Sunny WebBox and from there data can be transferred to Sunny Portal for graphical display and further analysis.

Optional accessories for the SMA Sunny Tripower X range.

Made with SunPower’s highest-efficiency Maxeon® solar cells, these portable solar panels deliver the most power and highest charging capacity in their product class.

Improves battery charging by using temperature at the battery for very accurate temperature compensation. (Included with TS-MPPT)

For crimping or soldering onto cables.

Terminals with PVC sleeve suitable for following size cables:
