Do Some Solar Panels Need Specific Controllers

A 16w panel could produce nearly 1a of charge current which is even more than a 10w panel.

Do some solar panels need specific controllers. Amps watts volts. The second fuse between your solar panels and charge controller is a little bit different to figure out. Before the pwm charge controllers there were some other types of charge controllers but you are not likely to run into any of those these days. A recent study found that solar panels are viewed as upgrades just like a renovated kitchen or a finished basement and home buyers across the country have been willing to pay a premium of about 15 000 for a home with an average sized solar array.

You may think why do i need a solar charge controller. Here are some settings in which solar plus battery can help and some in which sticking with simple rooftop solar panels could be the way to go. Here are the things we know. The controller controls and manages the current and voltage from the solar panels to your battery.

I am assuming that i do not need any fuses on the panels or between the panels and controller because the amperage and voltage will probably be well below the limits of the charger. We have 4 100 watts of solar panels totaling 400 watts of solar. A panel wattage of 10 of ah capacity or 10 of c or less would not need a controller. The size of this fuse is dependent on how many solar panels you have and how they are connected series parallel or series parallel.

Why do you need one. Well here s the thing. There are two main types of solar charge controllers. I am going to wire in series parallel.

If the panels are connected in series the voltage of each panel is added but the amperage stays the same. In some rare cases a solar panel can be connected directly to a battery without a controller. The controllers protect against overcharging overheating over discharging and overcurrent. Assume batteries are 12 6v.

The 30 in the victron smartsolar mppt 100 30 is the max resulting amps after the solar controller has worked it s magic. I ordered a renogy 4 panel 400watt solar kit with the 40 amp controller. Additionally there is evidence homes with solar panels sell faster than those without. The pulse width modulation pwm solar charge controller and the maximum power point tracking mppt solar charge controller.

Of course 10 of 160ah in wattage would be a 16w panel. Without a solar charge controller there is a high chance your solar batteries will overcharge themselves and consequently their lifespan will shorten. Had it not been these controllers many of these solar batteries could have been damaged. On an average the battery life is 5 10 years depending upon which battery you purchase.

Please heed all controller less solar suggestions with caution. The general guidelines are sometimes stated that. A 10w panel charging a 100ah battery. There are many different types of controllers on the market.
