I have a marine battery and Honda EX 700C generator for short term needs. I get 10 nights power on the battery alone. I wish to set up for long term SHTF. Any ideas on what solar panel I would need and the device to charge and maintain my battery. Also what battery is best. I’ve searched but the info is too general. The rear of my house faces south and gets great morning and afternoon sun. I am planning a semi permanent mount outside my second floor bedroom window.
Thanks Steve
