4 FAQs about Is 30a normal for 800w solar charging

Do I need a 20A charge controller for an 800W solar array?

For an 800W solar array with a 48V battery bank, a 20A MPPT charge controller would be the minimum requirement (since 800W ÷ 48V ≈ 16.6A). However, 20A 48V controllers are relatively uncommon in the market.

Which charge controller is best for an 800W solar array?

For an 800W solar array, an MPPT charge controller is clearly superior due to its advanced working principle and higher efficiency (up to 99%).

What size solar charge controller do I Need?

An 800W solar array is often paired with 24V batteries, making a 35A solar charge controller an ideal match for cottages, cabins, boats, RVs, and campers. However, the right charge controller size depends on your specific setup—including battery voltage (12V, 24V, or 48V) and the type of controller (PWM or MPPT).

What voltage should a solar array charge controller be?

Solar array voltage MUST be at least 5V higher than battery bank voltage for the charge controller to operate. Fix It by doing any/all of the following: None of the following charge controllers are recommended until this problem is resolved. WARNING! Solar Array Voltage higher than max charge controller voltage (250V).
