Hi,
I want to install a photovoltaic system with about 8 kW battery storage. I plan to do the entire installation myself. The house electrical system is being redone anyway, so the electrician will only need to connect the system.
Where would you recommend buying the equipment – online or from a local dealer?
If online, does anyone know any reliable sources? When you search for these, there are so many sites, but it’s hard to tell which ones are trustworthy.
Thanks

For me, it was a bit more. From the modules to the main electrical room, there was 25 meters (82 feet) of cable length to the room, and from the meter to the room it was 35 meters (115 feet). The battery storage and inverter are housed in an outbuilding. Chiseling, digging shafts, laying protective conduits, and so on.
I personally picked up the battery storage and only paid in cash upon handover. I bought the modules from a small local dealer, who then arranged delivery directly from Baywa to me via freight. I paid a 1,000 euro deposit and the rest once the Baywa delivery note was available.
I ordered the inverter online and paid via PayPal. Rails, mounts, plug cables, and so forth were all ordered online.
You need to watch what is available for delivery. The battery storage must match the inverter, and you should also get a suitable smart meter. There are plenty of modules available. If you absolutely need a Fronius inverter, it can only be operated with a BYD battery.
I now have the Huawei system and am more than satisfied with it. A year ago, there really wasn’t much else available. Still, I only managed to get one of the few available Huawei smart meters with some difficulty and without looking at the price. Others are also not compatible. So it’s important to have a solid plan.
Still, be cautious—there are many scammers online. I wouldn’t pay in advance to any dubious online shops. Goods against payment. Period.
Who connects the system doesn’t really matter. From the meter onwards, anyone can do what they want. For me, an electrical professional company did it. They installed an RCD (residual current device) before the system and sealed it. It was supposed to be commissioned by the utility provider. That same evening, I cut the seal and essentially commissioned the system myself.
The meter replacement took place sometime in November by a subcontractor of the utility provider. Not a word about the active system. Waiting would have cost me more than 2,000 kWh. Some people wait over a year. Completely ignoring the legal requirements.
Again, after the meter, I do whatever I want. Of course, everything within the VDE (German Association for Electrical, Electronic & Information Technologies) regulations. After years of everyone going crazy about the 600 W limit of a balcony power system, it is now possible to simply plug a system into a socket and feed power back into the grid.

Better do it yourself, that way you know what you have.
That is completely wrong and could encourage fraud or worse. Only balcony or plug-in systems are allowed to be connected by the owner. Larger systems must be registered by an electrician approved by the network operator. Payment is only granted with a new meter. However, installing a storage system demonstrates professional competence...
