ᐅ Evaluation of Solar Power System Proposal with Battery Storage

Hello everyone,

After several inquiries and offers, I now have what I consider the most cost-effective offer (see details below). I am still unsure about the "necessity" of the battery storage. I believe there is no clear "yes" or "no" answer here.

Based on your experience and what is known so far, is the payback of the battery storage guaranteed within the warranty period? I don’t think the battery will make you rich or poor, but you can make the most sensible decision now.

How do you evaluate the offer and the components in general? Does anyone perhaps have a comparable system and experience to share?

Photovoltaic system 11.9 kWp with 9.6 kWh battery storage

Produktliste: IBC MonoSol 425, TRI-STAND, Sungrow Hybrid HV SH10RT, Sungrow 3-Phasen Meter 80A

From what I’ve heard, there are currently major delivery delays for digital electricity meters.
Here, everyone receives a new meter very quickly, even when registering only a small solar system for a balcony or terrace.

Unfortunately, it still doesn’t work like that here. I waited nearly a year. I think it’s improving, but it can’t be denied. Our grid operator had the same issue.

But these are issues for the metering operator, not yours.

These disconnected statements from the forum troll simply lead nowhere...

Well, it depends. If you don’t receive a bidirectional meter for months and the system can’t be used because of that, it is definitely a problem.

That aside, you’re right 😎

You can feed electricity into the grid without a bidirectional meter. The network operator is obligated to accept photovoltaic electricity under the Renewable Energy Act. Yes, the challenge might be convincing the network operator to fulfill their obligations, but that should not be a reason for refusal.

Of course, it is possible to feed electricity into the grid without an inspection of the system and without a bidirectional meter.

However, this already places you in a certain area that can have legal consequences.

A grid operator’s inspection will not happen without a new meter. As already mentioned, there are thousands of photovoltaic investors who have been waiting for this inspection for over a year.

You’d better buy a rotary engine than give bad advice here.
