Re: 12V connection question (beginner)

Why use lamps with a built-in battery, the respective regulator and chargers will consume energy unnecessarily. Ideally the infrared sensors are not placed in the same place as the lamps. Instead, do wiring with DC 12V-24 V infrared sensor switches...

Re: 12V connection question (beginner)

The reference for the lamp is this one: https://www.amazon.fr/dp/B0CBVQ1XVM These are indeed lamps with battery, initially with solar panel (ridiculous size, probably 5W panel) and to be placed at the exterior. I wanted to place some in my garage, I took the cheapest ones, so...

Re: 12V connection question (beginner)

Uh the diagram does not show a connection in series but in parallel... :?: For me, no problem, it will work (as long as the 12V battery is not empty) Oops as well for me. At the same time, it seems to me that it is the amps that are dropping at the moment. Should I be careful...

12V connection question (beginner)

Hello everyone, I have a small 12V solar installation with battery with which I would like to connect motion detection lamps. - Victron 12V 66Ah battery - Fuse holder - 10A fuse - Voltage regulator (12V/24V to 5V 10A) - 6x 3.96Wh lamps (5V 0.8A to charge the...

AGM battery charging intensity?

Hello everyone, I have 3 Victron 22Ah AGM batteries connected in parallel. From what I have read, the maximum admissible charging current is 25%, or 5.5A for a battery. Given that I made a parallel connection, should I add up the total capacity (22Ah * 3 =...

12V circuit breaker for small photovoltaic installation

Hello everyone, I would like to place a 20A DC circuit breaker on my 12V installation, but I am confused about all the existing circuit breakers. Will a DC circuit breaker, whether 1000V 20A, 250V 20A, or 100V 20A, cut off in any case on my 12V installation if a current > 20A is released?

Re: Parallel and/or series connection (beginner)

If I understand correctly, putting panels in series means passing an equitable voltage through each of the panels, hence the fact that the 100W one which has a power lower than 140W risks burning out? No, they must all deliver the same intensity for a given amount of sunshine, otherwise the...

Re: Parallel and/or series connection (beginner)

1 can be put in parallel with a 140 W but not in series, because the 100 W risks burning out with too high a current and the 140 W will not deliver all its power. 4 PVs of 140 W can be put in series at the input of a Victron 100|20 MPPT Ok great, thanks for the info. If I understand correctly, m...

Parallel and/or series connection (beginner)

Hello everyone, I have 4 panels whose output I would like to separate into 2. A first parallel output at 12V to power all small equipment (telephones, razors, flashlights, etc.) and a second in series at 48V which will be connected to a VICTRON Energy Phoenix 48/500 inverter...
