The limiting factor on how much solar you can connect to a
Sargent PSU (Power Supply Unit) is dependant on the fuse that is protecting the
solar circuit. This is different depending on which system you have.
Below is a list of PSU series and the maximum recommended solar wattage
to be connected via the PSU.
EC325 – 120w
EC328 – 120w
EC400 – 80w
EC500 – 120w
EC600 – 120w
EC700 – 150w
EC800 – 150w
EC400+ - 150w
You can add more solar if you connect the extra panels directly
onto the leisure battery via a regulator and an appropriately sized fuse to protect
the circuit. The downside to connecting directly onto the Leisure battery with
your extra solar and not connecting it through the PSU is, you will not get a solar
reading on the control panel for the additional solar input.
Other systems in our range don’t have a solar input on the PSU's
so these would all need to be connected directly onto the leisure battery via a
regulator and an appropriately sized fuse to protect the circuit.
There is no limit to the amount of solar wattage you can install, if you are
connecting the solar directly on to the leisure battery.
