Standalone or Off-Grid Solar Systems are installed in situations where mains power is not available, or the client wishes to become completely independent of the grid. All power is generated by the solar panels; a battery bank stores excess power for use at night or when the sun is not shining. Sinetech has supplied the following designed and approved systems to customers. The most common configurations include:

Standalone / Off-Grid Solar System with Lithium-Ion Battery Backup
Key: 1) Battery, 2) Inverter/Charger, 3) Combiner Box, 4) DB Board, 5) Solar Charge Controller

Standalone / Off-Grid Solar System with Lead Acid Battery Backup
Key: 1) Batteries in Battery Cabinet, 2) Combiner Box, 3) Inverter/Charger, 4) DB Board, 5) Solar Charge Controller

Please note that all the systems depicted on this page have been designed by Sinetech's engineers using equipment and components that are tested and certified by us as being suitable for use in PV solar and backup power systems commissioned by us. Failure to use components other than those specified by Sinetech means we will not be able to guarantee the functionality of the system and may also result in inefficiency.
