I have 12 panels total, each are maximum 450 W generation. They are set up on two arrays. At this time of year each array could be around 255V ,1 to 1.4A ,and 300 watts in mid high sun conditions.
I understand the ac200 max can only receive 900 watts from the solar panels, with a mppt tange of 15 - 145 Volt and maximum 15 amp. I think my panels are over voltage, so is it true that I should not use them to charge up my devices directly? Could it be possible to charge the device using the DC Charge Enhancer DC50S connected to one solar array? Could I use a charge controller to limit the voltage coming from the panels to 145 or lower? This way iI can use my on grid solar panels in case of an extended power outage to charge these devices directly. Thank you.
Are you “Off Grid” or is the solar array grid tied to provide power to the home and excess back into the grid?
I have a 6.6kW roof array, also in 2 banks of 440W panels, 8 on one side of roof, 7 on the other. They are grid tied and I do not have a home battery installed. The house, in good sun, is self suffucient during solar output and excess is exported to the grid.
I chose to use Bluetti power stations via a generator transfer switch (internal to the home) during a grid outage. When the power stations are used, I recharge them during this time via the AC charging cable, which in turn is powered from solar. However in a Grid outage, I use portable arrays, which are well below max solar input, or a petrol generator and if needs be, a Charger 1 in my 4x4.
The key point here is,; As the rooftop solar is grid tied, I can’t tap into its output here in Australia. I’m not sure if there is a process for doing this as during a grid outage, the network authority remotely turns off solar. This is done to protect repair crews from back feed electrocution. It may be different wherever you are located.
In any event your output, as is mine, is way to high for the Max. My largest PS is the AC200P, and I normally run the house from AC180s, as high demand devices are not used during a grid out.
