This is my 1st post here. I am totally new to Solar and attempt to DIY my home solar system :
Now is about 80-90% completed, baby step at a time. It took me a really a long time to do this.
Pls recommend the most appropriate way to go for my DIY solar ESS batteries connection. Most of the parts are on hand while some are on the way.
The design is by myself and have people help to assemble the whole set-ups.
Here, I try to provide parts, sketches, design, pictures, specs info used in this project. So the gurus can clearly see & help answer according to my needs. I also try to upsize the parts re cables, terminal lugs, bus-rods, etc. to minimize current bottleneck & future problems. Most of these parts are from my old stock or bought cheaply for DIY sake. Since DC batteries matter to the mW and hundred of amps magnitudes, so it needs specific expertise where basic AC electricity familiarity are not all applicable here.
The whole 18PVs will be laid in one big plane all the way on the roof & the extended structure (with H-beam).
Since my roof is -30 slope but the sun perpendicular angles (my PVs) are between -35 to +20 deg, so I will manually adjust the panels accordingly. I arrange 3 PVs in a group, total 6 groups, so there will be 6 adjustment monthly. Adjustment is by cordless wrench, 20-sec per group. Not difficult. I even design/DIY a power stair for this purpose, again, liftable by cordless wrench upto 3.5m height. I bought a cheap stair of 1-m high & mod it with cheap bike parts & construction tie-rod. So, it is a 1-person operating equipment with small footprint when not in use. This liftable stair is not done yet but soon. It will be used for both adjusting the angle of the PVs monthly and clean the PVs as well. Actually, adjusting the PVs' angle do not require any stair, the adjusting mechanic can be accessed with 1 person standing on the ground and can be finished in 5-10 minutes for the whole 18 PVs. But cleaning PVs require power washer & some rubbing at certain spots, so stair is needed for spotless result.
