Please can i connect parallel 60amp and 80amp all mppt charge controller to charge a battery bank with different solar panel array input. Reply #4 Michael Goldberg commented 4 years 6 months ago I have a 150watts solar panel
How to select a solar charge controller for your PV
With a 100 to 150 watt solar PV panel, one can use a simple blocking diode from the panel, to pass solar PV power to the battery. This is interrupted by a high current relay to the battery and power buss to the telemetry.
Circuit Project: Solar Panel Voltage Regulator
Such a solar panel regulator should perform at least two operations: The obvious one is protecting the battery from overcharge at times of strong sun and little consumption, and the other is protecting it from excessive
Solar Charge Controller Sizing and How to Choose One
Charge controllers are sized depending on your solar array''s current and the solar system''s voltage. You typically want to make sure you have a charge controller that is large enough to handle the amount of power and
Solar Charge Controller Guide | All You Need to Know

The Ultimate Guide to Solar Panel Charge Regulators:
Good news: the basic process of choosing a charge controller is simple. All you need to do is determine the maximum current (I) in Amps flowing through the panels by using the formula Power (W) = Voltage x Current (A).
6 FAQs about [Photovoltaic panel current regulator]
Are PWM solar charge controllers good?
PWM solar charge controllers are quite cheap, and ideal for small-scale PV systems. Since these charge controllers operate at an efficiency of 75-80%, they can produce 25-20% power losses to the system. How do MPPT solar charge controllers work?
What types of solar charge controllers are available?
We feature a wide range of both MPPT and PWM solar charge controllers. See the BlueSolar and SmartSolar Charge Controller MPPT - Overview. In our MPPT model names, for example MPPT 75/50, the first number is the maximum PV open circuit voltage. The second number, 50, is the maximum charge current.
Can a solar charge controller be used on a 120V battery?
A select few, such as the Victron 150V range, can be used on all battery voltages from 12V to 48V. Several high-voltage solar charge controllers, such as those from AERL and IMARK, can be used on 120V battery banks. Besides the current (A) rating, the battery voltage also limits the maximum solar array size connected to a solar charge controller.
Do solar charge controllers have an upper voltage limit?
All charge controllers have an upper voltage limit. This refers to the maximum amount of voltage the controllers can safely handle. Make sure you know what the upper voltage limit of your controllers is. Otherwise you may end up burning out your solar charge controller or creating other safety risks.
Why do solar panels need a charge controller?
Since solar panels produce different amounts of electricity depending on factors such as weather conditions, the charge controller ensures that excess power doesn't damage the batteries. Without a charge controller, a solar-powered system wouldn't be able to function optimally, and the batteries would quickly degrade.
Do I need a PWM controller for solar panels?
Since PWM controllers operate with a switch only, the array voltage during operation is equal to the battery voltage. This means that you need to use nominal voltage solar panels with a PWM controller (36-cell panels for 12 V nominal and 72-cell panels for 24 V nominal).
