July 31, 20196 yr Hi everyone, Just sharing my installation thus far as I have learned a lot from you guys here on the forum. Installation consists of: 1x Axpert 5kw Inverter 4x Pylontech US3000 Batteries 15x 275watt JA Solar panels 3s x 5p (North at 25 degrees from horizontal) 160A Keto Battery Fuses / Disconnect 16A fuses on each PV string with a 63A DC Beny Isolator Have redone the complete main DB as it contained some very old circuit breakers and space was a problem. The whole house runs off solar except for the stove and hob (for now). I have a EV tube solar geyser, but have it on between 13:30 and 14:30 to heat up to 60 degrees with excess PV. Also have it switching on for about 30 minutes in the mornings. (Klerksdorp: Winter a bit cold🥶). So far everything runs quite good with between 50 and 60% left of battery capacity in the mornings. Maxes out at about 80% of the available PV power. Developed my own software to monitor the inverter and batteries 🤗. (still busy adding features) Some things still needs to be done like lightning protection and PV panel earthing 🤔. Attached are some photos. Feel free to comment or ask questions.🙂 Thanks Jacques
July 31, 20196 yr Cool gauges! And I like the green color of the inverter too Questions: 1) Were you able to discharge the Pylons to the bottom yet? 2) What's your low voltage cut-off setting, and does it cut the batteries when they are really discharged or too early? 3) How do you read the data from the Pylons? RS232 I assume... Thanks! Edited July 31, 20196 yr by Youda
July 31, 20196 yr Author 1. Lowest I went with Pylons were 23% 2. I need to check, but if I'm not mistaken it is on 44.8 V. I made it low so as to not interfere with my own control of switching to grid with SOC. 3. Yes, Rs232 on the console port. (I get SOC, voltage, amps, temp for all four batteries from the master batteries' console port) See attached photo showing data I'm getting-web page on phone. Still need to add some more data (over voltage warnings, AH remaining, cell voltages, etc)

Is it open source, or can we expect competition for ICC? I really like the look and feel of this. A friend of mine mentioned today how big a gap in the market there is for an open source product for the Voltronic Inverters.

When my Voltronic's DC board blew, the Beny tripped. I reseted it , and with the next one that blew it tripped again. Just don't reset them on a fault. First time I tried it burned away the contacts.
