**1st** I connected Batts (1,2 and 4) in parallel to charge and note that the voltage is decreasing to 15.34 although current is steady at 13.7A. This could mean the sulfation is breaking down and batteries are showing lower resistance.** Notable day** in that 1.26Kw was absorbed one way or another, and all three batteries had a few hours of >15V

**5th** Batts (1,2 and 4) Voltage dropped 15.6, 15.46, 15.38 with continuous 15A indicating hopefully breaking down of more sulfate and lowering of resistance. Final values are 13.63 @0.2A charge

**9th** Batts (1,2 and 4) Voltage dropped 15.63, 15.56, 15.37 (15.4, 13.9, 13.9) from 11:00hr to 15:37. Adding 1.3A load had no effect on voltage or amperage?

**10th** Around midday I rearranged all batteries. Batt4 becomes the regular load, Batt3 the secondary and Batt1 the reserve. Batt2 has been taken to Gavin's for a prolonged mains charge at 14.6V

All batteries required water, some especially Batt 1 was only just covering the plates so have reduced absorption voltage from 15.94 to 15.64 and float to 15.4

**11th** Batteries took best part of 1.03Kwh then at 17:25 disconnected Batts 3 and 1 at 13.11V 1W

**12th** All 3 batteries connected at 08:55 :: 08:47 Abs :: 10:08 Flo

Used Batt 3 with inverter with hardly any load. and surprised to see the voltage drop to 12.26 at 00:10

**15th** Collected Batt 2 from Gavin's having been on charge for three days at >14.5 taking 3A. Topped electrolyte up and connected all 4 batteries. The negatives are connected 4_2_3_1 The positives are connected 4_2 and 3_1 with a manual option between both pairs. All charging at 15.33 at 13.5A.

**17:33** B*4 V=12.6

**16th** All 4 batteries connected and MPPT Bulk/Abs set to 15.46V and float to 14.15V

**06:20** V=12.59 then used for 1 hour.

**17-19th** All 3 batteries connected Lowest 12.57V

**20th 12:75** Float V=14.03 @0.5A :: **12:49** Change Float to 14.5V ~ 2.1A :: **13:42** V=14.49 @1.9

**13:49** Change Float to 14.95V ~ 6.7AV ~ 2.1A **16:04** Disconnect Inverter and Batts 1 and 3

**20th** Float at 14.95V

**21st 13:20** reduced Float to 14.5V :: 3.2A = 4(0.8) @ 47W :: **16:52** Disconnect Batts 3 and 1

Batt 4 and 1 No load **16:55** 13.23v/3.2a :: 17:05 13.52/0.9a

**22nd 11:24** Float 14.49v ~ 2a **11:29** Connect Batts 3 and 1 dis at **16:42** V=13.84v

**24th 09:30** All 4 connected V=15.12 A=12.6 W=233 :: 10:35 Float @ 14.95v changed to 14.5v ~2.9a :: 13:38 V=14.49 A=2.2 @31W :: 13.39 reduced float to 14.15 :: 13:41 A=1.2

**25th 10:13** All 4 connected :: **10:41** Abs V=15.490 A=13.5 :: 12:35 reduced Abs to 15.4 :: 12:39 Float :: 13:12 Float to 14.95v :: 14:53 Float to 14.5v

**26th 09:42** All 4 connected Abs set to 15.64v :: 15:16 Disc Batts 3 and 1 @ 14.18v :: 17:41 V=13.61 Y=1Kw

**27th 08:45** Abs 15.62v :: Connected 3 and1, Abs, 08:52 V=15.30 :: 09:45 Float :: 10:00 dis batts 3 and 1, switch on inverter to use grinder.:: 16:00 no load reading ?? Yield 1.43Kw

**28th 08:30** Connected Batts 3 and 1 V=14.45 :: 08:50 Abs at 15.5v :: 16:23 disconnected Batts 3 and 1 :: With clouds on and off stayed on Bulk for most of the day and yielded a surprising 1.48Kw ::
