November 26, 20187 yr Good day. I’m new to this forum. I installed a Goodwe 4.6ES with 17 x 330w Canadian Solar panels and 3 x Pylontech Lithium Ion Batteries. It produces about 30kWh per day. Batteries are used at night and have about 30% SOC in the morning. Electricity bill has been reduced to R140 pm. Had a great electrician install it with a COC. Very professional and neat.
November 27, 20187 yr Hey @Leshen! Welcome! Like your install man! A fellow Goodwe lover! Add another two Pylontech's so that the SOC doesn't go that low... You will get more lifetime out of your batteries. Also, why don't you set it to mode 3 (backup)? My batteries basically sit by and idle.

I didn’t want to use Eskom at night, so the batteries takeover at night. If I had the opportunity to export power back to the grid and use the grid as a battery bank and turn the meter back, then I would just use the Pylontechs when Eskom is offline, but unfortunately I have a smart meter at home which is a shame.
November 28, 20187 yr Have you applied for the smart meter which allows you to be credited/ invert back into the grid? Those batteries are hellishly expensive and you would want to maximise your lifespan.

November 28, 20187 yr Author I think he is using Eskom at night which defeats the purpose of a Lithium Ion battery unless he is using Eskom as a battery bank then it makes sense. Edited November 28, 20187 yr by Leshen
November 28, 20187 yr Just now, Leshen said: I am using the batteries at night. If the batteries sit idle and only work when there is a power failure, then are you using Eskom at night? That's why I'm asking, because to spend R60k for standby in-case of power failure only seems overkill.

December 10, 20187 yr Hey guys! Yeah I had it in 'standby' mode. At the moment, I am pushing so much power back that I can run everything for a month without paying. I think I may have too many batteries; but then once again, if the power fails and is off for a few days, then I would be ok. I guess I can set it to use some batteries at night...
