have an application where i have a number of 50watt solar panels (2 to 4) that all have a different orientation towards the sun. is it possible to use several LTC4162's (one per panel) and have them all charge one and the same battery? if this is not possible: any idea how this would be possible?
If you won't be power limited by the LTC4162's 3.2A charge current limit, you could just wire them in parallel and input them to a single LTC4162. Otherwise, I see no reason that you could not hook up multiple LTC4162's to the same battery. Just be aware that each will only be aware of its own charge current delivery, so if enough power is available to charge your battery too quickly, the LTC4162's will not coordinate to make sure that it does not happen.
By "too quickly", I just mean at a charge rate beyond what is specified for the battery.
is it solved???? I have the same question.
if ltc4162's output voltage(battery charge voltage) is slightly different
How does charging work?
1. Only the LTC4162 with a slightly higher output voltage charges??(blocking diode)
2. output of two LTC4162 are tied together(input to battery) and the voltage is equalized, so both LTC4162s are involved in charging.
Is the configuration here with two solar panels, two LTC4162s, and one battery? They will both charge the battery simultaneously having reached some equilibrium charge voltage between the two. Both are involved in charging.
Three solar panels.
I tested(by using dc power supply) as your opinion and identify multiple ltc4162s are involved in charging.
