I’m sure I do but I see that link still works so if you’re signed in you should be able to download it. p.s. Not sure any of us ever managed to get any remote monitoring working if that’s what you’re hoping for?

Hi Coulomb, I've resisted so far in going the panel route as mostly its been going well being grid tied and having a 6.5kva Generator for the longer periods to keep the S-120 batteries happy, however I'm tempted to revisit this and add the 6 panels on to perhaps take both circuits I'm running off the inverter completely off the grid, these 2 circuits run almost nothing overnight - fiber ONT and 2 Wifi Routers (plus a PS3 if the son forgets it on) so the S-120s could conceivably run this side quite comfortably :-). One of the local supplies has these ( Still Polycrystalline but i doubt finding any other local stock within the right parameters): Maximum Power: 275 Wp. Power Tolerance: 0/+5 Wp. Maximum Power Voltage: 32.21 V. Maximum Power Current: 8.45 A. Open Circuit Voltage: 38.49 V. Short Circuit Current: 9.08 A. Module Efficiency: 16.53%. Looking at your calculations it seems these might just work, would you mind confirming if i'm on the right track: Coulomb Actual Vmp 37 32.21 Voc 44 38.49 Mulitplier 1.07 1.07 True Vmp 39.59 34.4647 True Voc 47.08 41.1843 Max Number of Series Panels 3.18606627 3.642164611 3S (V) 141.24 123.5529 Panel QTY (Operating V) 3.788835565 4.352279289 Panel Watts 300 275 Total Panels 5.333333333 5.818181818

Unfortunately not, eventually ended up giving up, I’ve got 2 battery monitors on the S-120s, it’s been faultless for the rest though.

Going to try link it again, just rescanned it and hopefully the forum allows 2mb Scan 25 Jan 2023 at 12.07.pdf

I’ll try scan it and post it in the next day or 2.

hahaha, i missed it, 🙂 good job on the sale.

Hiya - Reviving an old post, did you manage to sell this one?

100% these are clones, although fundamentally it works and has been doing its job perfectly i do in some part regret not spending the extra ZAR on another version to get the data side as well. On the PV side, what I get confused with is the Series / parallel connection, PV size etc, I would love to start with a basic set of panels that i can expand on but I'm yet to figure out / calculate what the minimum panel size / voltage etc i would need to look for and how many i could use.

From the Manual I have the following details (3000va 24v model). I would also be interested in advice on the PV recommendations for this. p.s. I eventually gave up trying to connect to the data port on mine (Tried multiple Apps, cables variations, Computers), would be interested if you ever have any joy on the Data Connection.

Having this same issue, last option is trying a old winXp Pc with a legit COM port, tried ICC as well as Watchpower but it’s as if there is no data on either the RS-232 or USB ports. Wonder if anyone has had any joy connecting to these 3kva units, kinda regret the impulse buy and should have gone the 5kva route perhaps.
