Well Guy's atleast for the next month I'm officially retired
just turned 60 and everything but 5K is coming from my super my way in the next week.So YES finally have time to finish some projects and also look to repair those MTTP boards as while working nightshift and making the boards over several months just let out the smoke on both of them.
So this week I will try and get both of them going again as this victron MTTP is boiling the hell out of my forklift battery to the point of a few cells raising so basically when the battery is charged current is still going in so a talk with the 12 volt shop is on the cards saying yes these 100/50 MPPT's do charge the batteries but they don't stop charging them.
I noticed just after lunch today after I measured the SG the batteries were full charged but the MPPT was still putting 30 -50 amps in the batteries.
Now as I have 99% of the parts to finally build a Mad Inverter I do have 2 choices to use that huge E-core where I have all the material to make the former or this toroid off the variac. Yes it far more work but less painful on the fingers to wind the secondary in my lathe than to rewind this toriod from the variac. Mike did say I could get away with using a of those HY5608's on the board which will leave enough for Mike's first board.
I do need to get some more soldering practice before I tackle Mike's new inverter board as all the parts still need to be ordered including new toriods from AEM where I have found yes the can do do a winding service.
So if I have to stack 3 toriods does one have to wind each toriod or can one span over all 3 do the same job. Also this would work out cheaper at AEM.
Also I'm going to stick on 24 volts as eh my 4Kw is going to finally get up in the air.
Repaired the door on the shearing shed today and that shed is going to powered up for the first time as I start my business. Bought 6.3Kw of solar and also got a 5Kw output grid tie inverter so the plan is use the the grid tie thru the day and switch if the output goes down on the grid tie.
Now I did get a quote for a 48V 1000AH forklift battery 10K for the battery and no charger. I have found out these are Chinese forklift batteries and they do come with a 5 year warranty so going with 12 of them for a 24 volt array will give give a new supply for the house as 12 years this 600AH has done our house and the upgrade does need to be done.
Well got enough questions for this post so...
