About this Gig
Need a solar charge controller or a battery protection board for your project? I design custom power boards that charge batteries safely from solar panels and protect them from damage, ready for manufacturing.
WHAT I OFFER
Solar charge controller design (PWM or MPPT) for 12V/24V systems
Li-ion, LiFePO4, and lead-acid battery charging
Battery protection (BMS): over-charge, over-discharge, over-current, short-circuit
Load output control with low-voltage cutoff
Reverse polarity and over-voltage protection
Schematic, PCB layout, BOM, and Gerber files
BENEFITS
Safe solar charging that extends battery life
Efficient design that wastes less panel power
Rugged layout with proper trace width and thermal handling
In-stock parts and files ready for the manufacturer
WHY CHOOSE ME
Focused on power electronics, not general PCB work
Clear communication and fast replies
Simulation and datasheet checks before layout
Free minor revisions until you are satisfied
Software: KiCad, LTspice, TI WEBENCH
Deliverables: Schematic (PDF), PCB files, Gerbers, BOM
Message me before ordering with your panel voltage, battery type, and charge current so I can confirm the best package.
FAQ
What battery types do you support?
Li-ion, LiFePO4, and lead-acid. Tell me your voltage and capacity.
What solar panel and current ratings do you support?
Typically 6V to 40V panels, up to 10A for standard packages. Higher current on reques
Do you design MPPT controllers?
Yes, in Premium. MPPT is more complex, so it takes longer and costs more.
What files will I receive?
Schematic PDF, KiCad project files, Gerbers, and BOM. Pick-and-place file on request.
Do you build or test the board?
No, I deliver design files only. Simulation and design checks are included.
