How we compare
the products.
What we review on each tab and why some models appear before others.
1. We start with the exact model
ASIN, power, phases, cable and accessories can change within the same commercial record. Therefore, we do not move a function from one variant to another without confirmation.
2. We use the same data for all
We compare power, current, phases, connection, control, connectivity, meter, declared protections and solar compatibility with the same fields.
3. We first place the reference marks
The first manufacturers with their own catalogue, manuals and locable support are listed and recommended. Then we evaluate the specific model. This does not guarantee that it is the right one for all facilities.
4. We distinguish the degree of certainty
A data sheet may indicate data declared by the manufacturer or seller, information visible in an image and characteristics that cannot be confirmed. When a data is missing it appears as "undeclared," "unconfirmed" or "verify variant"; we do not complete the gap in the same way as another model.
5. We do not pretend practical evidence
The editorial reading explains what use a product could fit in for and what it is appropriate to check. Unless expressly indicated, we have not carried out physical tests, electrical measurements or laboratory tests.
6. We review, but the information changes
Each sheet shows its review date. This date indicates when the summary was checked, does not ensure that the offer, documentation or variant remains the same. The destination and official documentation must be checked before purchase.
7. We do not publish static prices or availability
The price, the seller and the stock change. They are consulted on the destination page at the time of purchase to avoid outdated information.
8. The installation must be reviewed by a professional
A comparative does not replace the inspection of the installation. Selection and assembly must respect the equipment documentation, REBT, ITC-BT-52 and the specific conditions of the house or garage.
