Free delivery for Julian customers off Engineers Rd in Julian. Since the 2003 Cedar Fire, most residents are finding that the deep cycle batteries used for house power are not holding voltage. A great tool to measure a battery’s ability to function is a hydrometer (how to use a hydrometer).
The EZRed hydrometer is inexpensive and very easy to use.
Most Julian residents have a shelter to house the batteries and inverter. A recent customer showed me his battery revised battery shed where he can easily access the batteries for monthly maintenance.
A good supply of distilled water is vital for maintaining flooded cell 6 volt batteries
I met Aaron Ross from Ross Power Solutions who installed the solar panels and inverter for Julian customer.
