If you use 300W - 320W solar panels instead, then you just need 16 solar panels to obtain 5KW DC. How can I accomodate and where can I connect the batteries? Of course, you can disconnect the on-grid AC line to 'force' the inverter to switch to the off-grid mode.įor a solar project, we have calculated that we will need at least 20 x 250W PV panels for a 5KW to 6KW on/off-grid system with a total of 5 CyboInverters.

When the grid is down, it will go to the off-grid mode automatically powering AC loads. When the grid is on, it will be switched to the on-grid mode, sending generated AC power to the grid. An On/Off-Grid CyboInverter will either run in on-grid or off-grid mode, never at the same time. In an On/Off-Grid system configuration, will both the On-Grid and Off-Grid AC outputs be active at the same time? We do not want to include a battery charger in CyboInverters to keep the products simpler. We have a CyboCharger to charge 36V batteries.

You can use a solar charge controller or simply an AC battery charger to do this job. Please refer to the On/Off-Grid Solar Power System Design Guide to build your unique, useful, and exciting on/off-grid solar power system!ĭoes the On/Off-Grid CyboInverter contain a battery charger or do we need an external one? It depends on the AC standard of the electric grid for the on-grid mode and the AC loads for the off-grid mode.ĭue to the complexity and requirement variations, CyboEnergy has published an On/Off-Grid Solar Power System Design Guide, which can be downloaded after filling out a short form here. How do I design an on/off-grid solar power system in general? Is it dependent on the AC standards and AC loads?

This section discusses some of the practical matters for designing and installing an on/off-grid solar power system. Since its introduction, the On/Off-Grid CyboInverters have received a lot of interest and inquiries.
