The Manager30 supports up to 520W of solar input, and while larger arrays won’t damage the unit, it will only draw a maximum of 520W at a time.
Oversizing is beneficial, as it helps the system reach peak charging earlier, sustain it longer, and perform better in low-light conditions, ultimately delivering more total amp-hours into the battery each day.

What happens if I connect a bigger solar panel to my Manager30?
The REDARC Manager30 can accept up to 520W of solar input. Connecting larger solar arrays, for example a 960W array, will not damage the system, but the unit will only draw a maximum of 520W at any given time.
However, oversizing your solar array is not wasted. A larger system allows the Manager30 to reach its full 30A charging capacity earlier in the day, maintain it longer, and perform better in low-light or overcast conditions compared to a 520W setup.
Why is oversizing a solar array beneficial?
Even though the Manager30 cannot use all 960W at once, the extra capacity extends charging time and results in more total Amp Hours into your battery each day.
480W array: Delivers full 30A charging from approx. 10AM to 2PM
30A x 4 hours = 120Ah per day
960W array: Delivers full 30A charging from approx. 9AM to 3PM
30A x 6 hours = 180Ah per day
