You can use a buck converter module to reduce it to 12V. Many newer 12V inverters have auto reset so they will work seamlessly. Older ones just go into fault and have to be manually reset. With a couple 40V panels, you can feed many switching power supplies directly with DC.
I'd like to know how you calculate watts thru the day. Are you using theoretical power that can be obtained? For example, going to 2X the ideal resistance should greatly increase daily production.
That sounds like a good idea, but it isn't. Switching in an element usually drops the power in half. It isn't seasonal, but many times a day it is needed. Manual switching just isn't practical. Having a timer for the two peak hours at noon will see a slight improvement. Measuring current and...
I recently obtained a nice 12V ball valve and could imagine using this as a bypass when the water is hot. This ball valve only takes about 9ma to run so having it on all the time would not be an issue. A check valve on the instantaneous water heater input would provide enough resistance to...
You don't state what panels you have. Normally the power supply wouldn't care. Three 12V panels in series could exceed the output capacitor voltage specification as well as the diode.
It is microprocessor controlled that looks at battery voltage constantly with preventions from hot starts. Should it run too long it automatically shuts down and resets after a period. This prevents inverter faults from shutting down system. Freezers typically have short run times and the...
I took a totally different approach as I consider a freezer a battery. I have MSW inverter, an old car battery for starting surge only and run almost exclusively from panel power. Battery will only supply 5 minutes of runtime if sun goes away. Fridge only starts when battery is past float and...
Blown fuse is in the current shunt section and would not affect voltage measurment. Did you use the right connections on the meter. Short circuit measurements don't indicate much. Half the panel could have bad cells and still indicate correct current. Two panels in parallel could blow a 10A...
Because electricity is just magic to 99% of the people here and they just regurgitate what someone else has said.
For things that go arc in the night, get the bible on such things, Gaseous Conductors by James Dillon Cobine.
That is probably my most referenced book.
