Renesola inverters

[Haggers12]

Hi guys

Anyone have any experience with the above. I know renesolar known for their panels, not sure if their inverters are any good.

Considering the following:

How does this compare with the infinisolar 3/5kw plus? I know it has wifi but not sure what the benefit of DC switch is? Does this unit allow the same switch over between grid and solar as the infinisolar?

Thanks in advance
Haggers

Subscribed. Also interested in one of these.

You are aware this is a Grid-Tie, not a Hybrid Inverter right?

This will take PV power, and send out 220VAC. At night, there will be no power (no sun). There's no batteries.

It either generates power during the day (when the sun shines), or it does not generate power.... Finished.

So during load shedding (at night), you'll be without power. At night, you will be without power. During a cloudy day, you (could) be without power if there isn't enough sunshine. Grid-Tied inverters, generally also switches off when their supply (mains) Voltage is disconnected, i.e. during load shedding.

Unless you plan to add additional charges / inverters / batteries / etc. you won't gain much with this. Ideally, you'd want a Hybrid "smart" inverter...

I don't know why people bother using Grid tie inverters. Pehaps it's fine for an office, which doesn't have night time staff, but as Chris said you would be without electricity if Eskom fails, and it's a cloudy or rainy day.

Grid tied inverters are ACTUALLY for feeding back into the grid via a 4Q meter.
Just because it's grid tied doesn't mean it can't function without grid power.
And you can get grid tied inverters that also manage batteries etc. (Just not this one)

I personally, haven't seen one grid-tied that won't switch off when grid power failed (i.e. load shedding)... There are reasons too why they shut down.

Yes, grid-tied does have a place in the market, in our unique market however that place is very, very limited. Also, a grid-tied inverter uses the grid as batteries (there are no physical batteries). As soon as you add batteries, it becomes a hybrid inverter...

My point, exactly. And then you could have brought a hybrid inverter at half the price, with twice the convenience

Looks like a Replica of the infinisolar but with higher output than for eg the 3kw version. Seems limited parallel also allowed?

Awesome. Much has been learned. I did not know about the difference between Grid-Tied / Hybrid.

Why dont you just buy the axpert unit like most others looking for a cheap inverter?

 

[Haggers12]

Hi Beachless,

I am planning an install for September, so I am doing my homework before I spend. Just want to understand all my options.

Axpert is one of my options as I can get them cheap locally and they can be paralleled. Main drawback is the switchover between grid and solar pv.
