solar

I have a solar system with an on-grid (grid-tie) inverter, which only works when there is an active grid supply. Unfortunately, I live in an area where there's no grid power for most of the day, so my solar setup goes unused during that time. Buying a new hybrid inverter is quite expensive and...

Can someone help me with this? Solar-Powered Smart Street Lighting with Motion Detection 1. Determine the required solar panel size, solar charge controller (Maximum Power Point Tracking) / BMS (Battery Management System) and battery storage capacity to ensure continuous operation of 12 V, 37...

Hello, as the title states my objective is to wire in parallel the output from two or more MPPTs, to charge a battery and power a load at the same time. As far as I understand to parallel two normal DC-DC power supplies there must be some sort of load sharing or synchronization capability, but...

This is a purely hypothetical question. Lets say I have a solar panel and I make an "inverter" that produces a 340V (680Vpp) square wave and can perfectly sync with the grid. Since a 240V grid has a peak voltage of 339V my inverter's output is always higher than the grid's voltage, so if I was...

I have been "playing around with" some DC boost switching regulator designs for use in a solar panel DC-DC converter typically 33V to 48V. Typically I use a switching frequency of about 150Khz and an inductor of around 68uH - this seems an OK compromise for switching time losses, current ripple...

Consider a generator and a inverter. Generator is producing power at 50 Hz and the inverter is producing power at 50.3 Hz . Both of the sources are supplying a common load. From which source the load will take power first?

Hi Im a complete novice here, very new! My history is Im a paramedic but recently diagnosed with autism (lots of social issues for me!). But I often get an intense interest in certain areas (autism!). What I really want to do is try and build a few low voltage electronic circuits. 1/ A...

I have a solar pane that gives about 12 volt and 120 mah and I want to make a 3.7 v battery charger. I dont have a voltage regulator I just have transformers, resistors and capacitors ect. and I dont have a much knowledge about electronics. Please can you send a circuit? Thanks.

I want to build one of these, I know I can build one but we all know there is no fun to be had there. I am thinking either pico-w or ESP32 with a web frontend, for the bit I know less about some questions 1/ For the solar panel is there anything I need to be aware of? Waterproof, power etc or...

Hello, I need to repair this PCB. Do you think this board can be repaired without having access to a diagram? From the image what components do you think are burned? I'm a newbie, but where I live I cannot find any place where to repair circuits and I cannot have a replacement board because...

So I've got a game cam and a 5V 4W panel that I'd like to add to the cam to help maintain the 8 AA's a bit longer. The cam holds 8 AA's but only runs off 4 meaning 6vdc. I haven't taken it apart yet so I'm unsure how it handles the other 4 batteries.. electrically speaking. Anyway so the idea...

Hi, I am looking for some advice - I have a CCTV system running in my garden workshop using approximately 11W, running from a small UPS connected to mains power. On the roof I have a 19V 40W solar panel connected to a charge controller charging 12V battery. That is hardly being used so I want...

Greetings fellow electro-heads! First-time member/poster here, so I'm hopeful for a warm welcome! =) I am currently designing a fun personal-vehicle project involving an electric catamaran/quad amphibious vehicle, and I am reaching out for some advice about the powertrain possibilities for a...

Yeah, so I'm using the XL4015 with a 100w solar panel. I have the XL4015 set to 7.35vdc to charge a SLA 6v lantern battery. The diode is working, but the current is limited to 200mA, instead of the full 300+ mA it would get if there was no 1N5822 diode in series, to prevent the darkness at...

Hi, I have a project that i would like to complete. i need to activate an LED light outdoors, whenever a designated vehicle comes within 200-300metres of the LED light. i was thinking of using a simple 12v FM radio transmitter on the vehicle. the LED would have an FM radio reciever tuned to...

Hi all, I have a Solar LED Light that is not working, and I want to use this to get back into electronics a little. I'm a Control Systems designer, but this level of electrical work still creates a lot of confusion for me. So I am hoping to use this as a learning project. The board is a...

Hope you all are staying safe and healthy. The Pandemic lockdown has forced us to work with the only components we have at home. I am working on a battery-operated esp32 pico board having other sensors hooked up to it that need 5v of supply. So I connected two rechargeable 3.7v Li-Ion batteries...

Hi, I want to rotate the motor directly with solar. My aim is to change the speed of motor depending on amount of light on the solar. I do not wish to use any other power supply. I want the motor to rotate solely with Solar only. this is a very small project for high school students. What I...

Background I'm working on a seismic alert network and seismograph station at my school in Puerto Rico. We're building a solar system for the system to continue running during a potential seismic event. The system only consumes about 10 Watts, but with the satellite internet equipment it might go...
