I have tested it before with an ordinary car battery, and it worked. That battery was a year old. so I thought a marine battery would be better. I know I need a good battery bank. That is why I am attempting to cut my bill help me save more to achieve that goal in a shorter time. If I get to save 2kw per day, at the end of the year I can buy 4 gulf cart batteries with the savings alone. That's why I am determined to having the system up and running.
Any way burrowed a 2 farad cap from a friend last night put it close to the inverter , will have more time on the weekend to see if it really helps.

I am not looking to store and use. I want the battery to do what they say these type of battery was designed for, to deliver a burst of power in seconds, the way I set the system up, the battery does nothing after that, well take back some charge (like starting a car). When the fridge is running it consumes 150w to 160w. At times the array produce 200w plus by 10am at mid day 600w to 700w.  I just have to keep fighting with it until I get it right. I know that at the end of the day to get the best out off the array is to get decent batteries. but that's not now. Thanks for the advise.

its not written on the battery, but here is whats on it 600 CCA, 160 min RC and a search on the internet tells me it is 60AH
The inverter 2000W surge 4000W

They where in series, but they were no good. What I am trying to satisfy is the start up need of my refrigerator. Whenever it starts up the battery drops below 10v and the inverter shuts down (low voltage protection). I thought the CCA of the marine battery would take care of that. instead of waiting to buy the right batteries, I would  used the system until then. Not thinking about storage now, just when the sun is up I can run a few things and the savings go towards buying the right batteries. I designed the system that it switch between the grid and the solar system automatically when the battery is below 11.5v for 2 minutes switch to grid and switch back to solar when at 13v.

Hello guys,
I am trying to restart my system and cant afford to by the batteries that I need new now. Bought two used Rolls 6V 450AH from another guy who upgraded his system had to give them back. Whenever the fridge starts up my system shuts down, the batteries could not stand up to the surge. Bought a marine battery thinking that 675 CCA would do the trick, it did not. What am I doing wrong here? For now just want to deliver power to some appliances when the sun shines until i can put enough money together to build a decent system. Have three panels 270w each, charge controller XW-MPPT60-150 and a noname Chinese inverter . Took me six years to get this far bought one at a time, electricity cost in Jamaica is too high have to get of the grid somehow.
Any advice will be appreciated.

I suspect that you're using a Modified Sine Wave Inverter.  The solution then is to switch to a pure sine wave inverter.

I am in low income earner in Jamaica, going for a pure sine wave inverter is going to kill me now

Even when the higher wattage lights are on, the radio and the lower wattage bulbs wont come on. The inverter does not have the sleep feature. the inverter is a WAGAN 1500 (3500 surge) It is kind of strange to me!!!I am typing now with the lights on, and the radio won't come on, use to work.

Hello,
   I have a system setup and running for the last five to six months, four gulf cart batteries, 170 watt solar panel, 1500 watt inverter and a solar boost 3024i charge controller. Five days ago my radio stops working with it, but will work fine on the grid. I though several of my 5 watt cf lights blew, but they worked on grid power as well. The higher wattage cf lights worked on the inverter (14 and 22 watt). Does any one know why this would happen?

Thanks for any suggestion.
