Is there an inverter that can invert and charge at the same time over the same cables?
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

Can I connect my 12V appliances to a 48V battery bank?
No. You would need a DC to DC converter to step down the voltage.

If I need a 36V Cotek power supply, can I use a 60V Cotek power supply if that is all that is available?
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

Are Cotek power supplies stackable?
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

Why does my OutBack Power Radian Inverter keep turning off after I've added a pump?
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

Can I install the Morningstar TS-M-2 and the Morningstar TS-RM-2 meters together on the same Morningstar charge controller?
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

I have solar panels with 9.7A and 37V. 4 panels in one series will be 150V, but two series in parallel will be 20A. Would either scenario work with the SMA SB3.0-1 SP-US-41 Sunny Boy Solar Inverter?
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

Can I connect 2 strings of 15x 400 watt, 40.3 volt panels to the Fronius Primo 11.4-1 Solar Inverter?
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
