Photovoltaic Panel Voltage Converter: 37V DC to 12V Battery & 37V-230V DC-AC Inverter for Bulbs

Hello!
I came into possession of a photovoltaic panel and I want to use it to charge the battery on the plot, but I have a problem
I read the voltage 37V DC from the panel, so I'm a bit afraid to connect it directly to the 12V battery
And I would like to make a DC-AC 37V-230V voltage converter (so that I can light an ordinary light bulb in the house, not a car one).

And rightly so. But you can charge the battery - there are special charge controllers for PV panels for this.

If you want to power something with it, you need to add a battery as an energy buffer, because the performance of the panels varies over time and depends on weather conditions. There is a whole lot of ready-made solutions on the market, and in a wide price range. By the way, IMHO better to install all equipment on the plot in the 12 V version because then we have a simpler power supply and lower energy conversion losses.

A 0-37V / 220V converter powered directly from the panel without a battery does not make sense. It will work only in a cloudless sky, when you get enough power from the panel to power the "light bulb" + own losses. Then it is better to make an additional window or skylight in the gazebo and you have natural light.
When it is cloudy or it is dark, the gazebo will be dark.
You have to buy a ready-made driver module or a 20-40V / 12-15V stepdown converter and use at least an old car battery. You can make an inverter, but if you have no experience, it is faster and cheaper to buy a ready converter module and make the housing and cables yourself. 12V LED "bulbs" are generally available.

As colleagues wrote above, you need to think carefully about what you want to get. There are basically two solutions:

1) Step down charger for a 12V battery and then you can stay at 12V or add a DC 12V - AC 230V converter
2) How do I understand 37V has been measured without load? Then this PV is dedicated to work with a 24V battery. You can then use chargers for 24V PV and batteries for 24V and a DC 24V - AC 230V converter

Each solution has its advantages and disadvantages. On the plot, you can easily do without 230V and personally I would go in the direction of powering 12 V bulbs without AC converters. Not only light bulbs, there is a lot of equipment for drivers, from refrigerators, starting with TV, working on 12V. Most use a cigarette lighter, just add a few such sockets to the battery, and in addition to light, we have power to many other devices. By the way, I am now making an emergency CH pump power supply system with an AC 230V converter, but I added a few cigarette lighter sockets to the battery, they may come in handy sometime.
