Solar Panel Inverters and Batteries query

Aidan17

Hi,

I have a question regarding Solar Panel Inverters. I received two quotes from the same company, my initial quote was for €9,200, when the called to do a site survey they enquired what my cheapest quote was and then beat that by €100 and quoted me €7,300.

I asked them to put all the details in writing and to send me datasheets on the products being used. I already had these from the first quote I received and I now notice there are different inverters and batteries being used for the cheaper quote and I wonder are they inferior to the original ones I was quoted for.

Original Quote: €9,200

Inverter: RHI-(3-6)K-48ES-5G

Battery: Product Dura5

2nd Quote: €7,300

Inverter: S5-EH1P(3-6)K-L

Battery: Product DURACELL 5+

Both are solis inverters with the second one being the more recent one.

I think both batteries are the same.

Pure drive batteries recently rebranded as Duracell (possibly to get a bit more brand recognition).

That's a huge reduction on initial quote. Quite scandalous that they can drop to that.

Thanks. Yes I know, and for that reason I want to say no to them and go with the next nearest quote, but they have not sent me their quote in writing yet.

Hi, would you know which is the better inverter the first one or the second one?

thanks

Practically the same inverter

Second one as it's newer. (Possibly don't get the first one anymore)
