Charge controllers

A solar charge controller protects your batteries and optimises charging between photovoltaic panels and storage. To choose, you can opt for a PWM if you are looking for a simple and economical solution, or an MPPT to maximise efficiency (maximum power point tracking).

Always check the battery voltage (12V / 24V / 36V / 48V), charging current (in A) and useful options (display, monitoring, protection) for your installation.

  • MPPT: preferred for maximising production and better managing voltage variations in the panels.
  • PWM: a simple solution for small systems and tight budgets.
  • Compatibility: check the battery voltage (12/24/36/48V) and charging current (in A).
  • Safety: choose a model with protection and, if necessary, monitoring (screen/interface).

FAQ - Solar charge controllers

1. What is a solar charge controller used for? +
A charge controller protects your batteries and optimizes charging between PV panels and storage for a more reliable system.
2. What is the difference between PWM and MPPT? +
PWM is a simple, cost-effective solution. MPPT aims to maximize yield by tracking the PV maximum power point (useful when conditions change).
3. How do I check compatibility (12V/24V/36V/48V)? +
Check your battery bank voltage (12/24/36/48V) and pick a controller compatible with that voltage.
4. How do I size current rating (A)? +
Size based on required charging current (in A), depending on your PV and usage. Higher current requires a higher-rated controller.
5. Which options are useful (protections, monitoring, display)? +
Depending on your system, choose suitable protections and, if needed, monitoring (display/interface) to secure and track charging.
