The number of solar panels you can safely connect in series depends on the voltage limits of your MPPT charge controller or hybrid inverter. There are 2 key boundaries to consider: To ensure your system starts charging efficiently, the series voltage must reach at least the MPPT’s start voltage.
For example, if you connect three 12V solar panels rated at 5A in series, the total voltage becomes 36V, while the current remains 5A. 1. The increased voltage in a series connection reduces power loss (P = I²R) and minimizes voltage drop, improving efficiency over long wire runs. 2.
Understanding the differences between solar panels in series vs parallel connections is vital for designing a solar system that maximizes performance and longevity. Series wiring increases voltage and suits high-voltage applications but is more affected by shading.
Generally, for RV solar setups, solar panels usually have an open-circuit voltage (Voc) between 18V and 24V. MPPT charge controllers commonly used in RVs support a maximum input voltage of 100V to 150V. Based on this, you can typically connect 3 to 6 panels in series.
