No. Power cannot flow along the battery cables both ways at the same time. In other words, inverting and charging cannot happen simultaneously over the same cables. If you need simultaneous inverting

No. You would need a DC to DC converter to step down the voltage.

Yes, you can use a higher voltage power supply (albeit at a lower current output) because all Cotek power supplies offer fully programmable current and voltage settings. For example, if you use a 4

Yes, all Cotek power supplies are stackable including the: AE-800 Series AE-1500 Series AE-3000 Series AEK-3000 Series This means two AE-800 Series power supplies stacked may provide you with

One of the primary challenges pumps can present to any inverter is that the pump's locked rotor current can be five times the inverter's nominal power rating. If your inverter is too small, you may no

Yes, you can use both meters at the same time on one controller. Simply connect the controller meterbus port to the port labeled TriStar on the TS-M-2, then connect the TS-RM-2 TriStar port to the Met

1 string in series at 150V would work, but it may be late in the morning before it starts up since the minimum startup voltages are 100V / 125V on a 208V / 240V system respectively. 2 strings of 2 pan

No. At 604.5 volts per string with 15 panels on each string, you would be exceeding the inverter's capability. Although it may work sometimes, during peak season, this is likely to cause issues with y

Yes, you can AC couple SMA Sunny Island inverters with other brand inverters or generators.
