## Solar Battery Charger Design Help Needed

solar Battery charger Design Help Needed Hi I have designed this solar Battery charger. A 12V 75W solar Panel will be used. So, current will be max 6.25A Charging current of SLA batteries is 10% of its Ah rating. So, This charger can easily charge a 12V 40Ah battery. 1. Is (...)

Hi, I'm looking to build a solar charge controller for lead acid battery rated 35Ah. The panel is rated 200w at 24V. I haven't yet built this circuit other than playing around with the example buck converter circuits on LTSpice. I would want to have a prototype running on the breadboard first. Have following questions : 1) My (...)

Hi, I'm simulating this circuit of battery charger in Proteus and wondering how to convert the result into decimal numbers. Like 14.42 V instead of 14420 mV. PIC Simulator IDE code: 'PROGRAM TO CHARGE lead acid BATTERIES WITH solar PANEL 'USES PIC 16F877 AT 4 MHZ 'AUTHOR SANTHOSH JAYARAJAN 'NOTES: (...)

## Choosing a suitable PIC microcontroller for a solar charger

Hi All, I'm planning to build a PWM solar charger for home use with flexibility/scalability in mind. I'm a beginner with less experience in pic programming. I expect to incorporate the solar charger with below features. 1. Based on PWM algorithm 2. Charging multiple 12V sealed lead (...)

## How to design 20A 48V MPPT solar charger

1. investigate your batteries, a nominal 48V battery (lead acid)will require 56 V at least to fully charge it. 2. This means that your solar cells must produce greater then this for maximum charge. 3. If you intend to charge at 20 A,for long life your batteries should be rated at least as 200 A/h Frank

## solar charger technique and tutorial

Hi, Some technical informations needed - What battery chemistry - what battery voltage - what battery capacity - what solar cell max power You say you want to design.... is this your design? Or do you want to build it this way? If not: why do you want to change something? What are your goals? Klaus

## LTC3780 for MPPT solar charger poblems

Hi there, I have some problems using LTC3780 for charging an lead-acid battery. I did manage to make a working buck-boost power supply with LTC3780 using the schematic form datasheet(for tests I managed to get 12,7V at 48W from 7-18V supply), but having it charging a battery from PV(power supply simulated) module failed. The symptoms are: 1) V

## Solar Battery Charger

I am trying to do a solar charger to charge up a lead acid battery. My solar panel will generate a about 22V and 0.24A with about 5W power. Is it possible to charge up a 12V batter. I found out some circuit diagram in internet but most of the solar panel have a 10W power.

## MPPT for photovoltaic application (using microcontroller)

Dear All, I am planning to implement an MPPT algorithm for solar powered battery (lead acid, 12V, 7Ah) charger. The solar panel is a 50W one. At peak power it can give 18V and 2.78A. It has a Voc of of 21V and Isc of 3A. I have some querries regarding the design I plan to do, which are: 1. Which (...)
