This System was designed as a grid tie system.
The installer needed to AC Couple to a DC Inverter. We came in and Solved this Issue.
Notice the Addition of Charge Controllers, Breakers, Lightning Arrestors, &  Progress.

THIS IS THE 12 VOLT SYSTEM TESTED and RE-CONFIGURED SEVERAL TIMES. ORIGINALLY 4 100 WAT POLYCRYSTALLINE WERE OK BUT AFTER ADDING 2 MORE MONO CRYSTALLINE PANELS, (FROM 1 STRING OF 4 TO 2 STRINGS OF 3) THE BZ CONTROLLER (LIMIT 500 WATTS) AND THE 12 VOLT RAMSOND PURE SINE WAVE INVERTER SEEMED MORE SUITED FOR AN RV OR CAMPING. SHOWN IS 3 100 WATT MONO-CRYSTALLINE AND 4 100 WATT POLYCRYSTALLINE ARRAY. (NOTE THE ODD PANEL WAS USED FOR ANOTHER TEST FOR A SMALLER 12 VOLT SYSTEM). NOTICE THE SOLAR POWERED MOTION ACTIVATED WIRELESS CAMERA. ALSO THE SMALLER 12.6 WATT PANEL FOR SOLAR POWERED ATTIC FAN. 6 TROJAN 6 VOLT T-105 RE-WIRED SERIES/PARALLEL 12 VOLT FOR 660 AMP HOURS.

This SOLAR Off-Grid System Was Just Converted From 12 to 24 Volt. ON ANY CHARGE CONTROLLER, HOOK UP THE BATTERY TEMPERATURE SENSOR. SAVE YOUR BATTERIES FROM OVERCHARGE BURNOUT! WHEN BUYING ANY INVERTER MAKE SURE THE VOLTAGE IS 120 VOLT. DON'T BE FOOLED BY 110 VOLT OR 115 VOLT RATING. THE plus or minus 5% CAN DROP YOU VOLTAGE AS LOW AS 106 VOLTS AC WITH NO LOAD. Pay attention to the Inverter's specs. 24 volt and 48 volt systems are more efficient than 12 volt.
The larger 24 volt and 48 volt systems can have single phase (2 hot legs) power in 1 unit. I don't recommend stacking inverters. 
The top inverter is just sitting there. THIS IS NOT STACKING INVERTERS! LOL
THIS MOUNTING HARDWARE IS SLICK AND WILL NEVER RUST! 6mm HEX WRENCH REQUIRED.
THIS 4 100 WATT POLY CRYSTALLINE ARRAY WORK WELL WITH THE 12 VOLT SYSTEM. ANY INCREASE IN PV WATTS IS MORE EFFICIENT GOING TO 24 VOLTS. TESTING MPPT VS PWM ON THE SAME PANELS, MPPT IS BETTER! SCHNEIDER (TRACE) C40 PWM CHARGE CONTROLLER WITH REMOTE AND BATTER TEMPERATURE SENSOR.
2 6 VOLT TROJAN T-105 RE IN SERIES TO 12 VOLT CONFIGURATION.
MODIFIED SINE INVERTER FROM SAM'S CLUB.

This DIY SOLAR PANEL ARRAY was finished just in time. The day I completed all hook-ups and charged the 6 Trojan T-105RE Batteries, A Storm came up and the grid power went out. My basement leaks during flash flooding and is one of the reasons for the need for an alternate power source. Just as the rain and hail came down in buckets, it was hard to believe the panels were still charging the batteries (MPPT). Then my basement started leaking. I hadn't planned for this to be the test, but I plugged in a light and my shop vac and kept my basement from flooding. Now I have a fail safe for my sump pump and small power needs. I'm waiting for technology to affordably redo my roof with PV Roof Material.
THE HOLE
I DUG THE HOLE EVEN AFTER THE 4 FT DEEP 80 FOOT FRENCH DRAIN TO PUT IN A SUMP PUMP. AFTER SEVERAL AC PUMPS STILL NOT STOPPING THE LEAK ON AC, I  DECIDED TO DIG DEEPER AND GO 12 VOLT NOTE THE 12 VOLT SYSTEM WITH A MARINE BILGE PUMP AND FLOAT SWITCH KEEP THE WATER PUMPED OUT OF THE HOLE WITH A HEAD OF 6 TO 7 FEET. WHEN IT DOWNPOURS THE BASEMENT STILL LEAKS. THE HOLE FILLS VERY QUICKLY WITHOUT THE PUMP. THE UNDERGROUND WATER TABLE RISES IN THESE HILLS.

THIS SYSTEM HAS BENN GOING SINCE 1997. A 400 WATT WIND TURBINE WAS ADDED RECENTLY. THE BP PANELS ON THE LEFT WERE MANUFACTURED IN 1997. THE 100 WATT MONO CRYSTALLINE PANEL ON THE RIGHT WAS ADDED LAST YEAR WITH THE MIDNITE SOLAR BREAKER BOX AND LIGHTNING ARRESTOR.. TRACE (SCHNEIDER TODAY) CONTROLLER AND MODIFIED SINE WAVE INVERTER HAVE PASSED THE TEST OF TIME UNDER THIS MOBILE HOME ON 100 ACRES AS SOLE POWER SOURCE. THE TROJAN L-16 RE B BATTERIES WERE A SOLID INVESTMENT FOR 2013. CUSTOM ARTICULATING PANEL ARRAY FRAME by VETERAN GLASS. NOTICE ADDING 2 MORE 100 WATT PANELS TO THE ARRAY. THE WIND TURBINE AND ALL 6 PANELS POWER THE 24 VOLT THE OFF-GRID CABIN SYSTEM. THE SHED SYSTEM HAS TWO 1997 UNI-SOLAR PANELS, 24 VOLT FLEXCHARGE CHARGE CONTROLLER & THREE 8 VOLT GOLF CART BATTERIES. THIS SYSTEM IS 24 VOLTS. NO 120VAC INVERTER. 24 VOLT 3450 LUMENS OUTDOOR LED LIGHTS ARE VERY, VERY BRIGHT!
