Hi Guys,

Find attached a pic of the Solar UPS project that I am currently busy with.
I have done and tested all the connections available on the pic and everything works great. Only one simple question?..

Can the 2 outlets of the UPS's be connected together as one output?

I doubt it Ul, as the idea of connecting two power sources in parallel owing to slight imbalance generally runs the risk of one feeding into the other, both overheating as a result

But we'll know soon enough; we have some actual engineers here at a2k

@dalehileman,
I have read some articles similar to your response.
Let's hear from those actual engineers.
Here is more or less the same idea of outlet I found on Google.

@Ulrich,
Please note though that the Output power is from two exact same output sources.The UPS's are exacly the same. If this counts for anything..

Ul, you'd have to try it: Before connecting the two secondaries in parallel like that, with no load on "AC OUTPUT," connect an ac milliameter in series--the lower the reading the safer

Or just turn it on and see, with nothing else connected, whether they get hot
