Can I use wind and solar in the same combiner box?

Posted by Frank Molina, Stellavolta on Jul 12th 2022

Can I use wind and solar in the same combiner box? For example, a wind turbine with 3kw and a solar panel with 2kw to be connected together using the combiner box to produce a single output of 5kw.

I have a fault code 581 on my new Fronius Primo. How can I fix it?

I have a fault code 581 on my new Fronius Primo that says the unit no longer meets IEEE 1574.1 standards and the Special Purpose Utility-Interactive setup will be activated. How do I correct the fault

Can I replace my 12 year old VFX3524 with a newer model VFX3524M?

No, the VFX3524M model is not backwards compatible with the older model VFX3524. When stacking OutBack Power inverters, both or all inverter models need to be same model number and firmware versions.

Can I use a combiner box for separate solar arrays with separate charge controllers?

Yes, you can use a combiner box for separate solar arrays with separate charge controllers, as long as you stay within the voltage and ampacity limitations of the combiner box.

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.

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
