  1. I've seen it with both the sizes I run (single phase AC). I've just accepted it - had wondered whether the spec referred to the output power, rather that input. It are wot it are:) Ian
  2. Hi DIY, they generally draw a lot more than their rating, so it's probably normal. That's from my experience. Ian
  3. Hi Chris, here's some info on our experience re boreholes on our farm. When we bought we had several remote boreholes powered by expensive DC pumps coupled to a few panels, running all day like you have. Our main issue became theft, as the panels and then pumps became targets. I moved to running 220V from the house to the pumps, and installing cheap 220v pumps at the sites. I was then able to control the pumps via smart switches as a bonus, and the thefts disappeared. 300m is a long run, but you could use a smaller pump to reduce the loading and guage of wire. 10% losses in the cable are acceptable IMO. The fact that you want to time the pump implies it's bigger than abs necessary? We're off grid, and all the pumps are supplies by our home setup. Cheers Ian
  4. Maybe something is salvageable if you can break down the batteries and rebuild using the good pouches? Depends how bad the situation is, and whether you are tech savvy. For a bit of inside info:)
  5. Hi Wesley I recently disposed of Gel batteries at SA Metal Group in CT, but they have branches all over. Decent price/kg, just have ID and get your cash. Cheers Ian
  6. The genny is floating. SA1. Yes, all 0. SA2/3. The battery is set to PYL, and comms seems good. Except, now it occurs to me that there is a 70 fault reported. So perhaps that's what's preventing charging???? The manual states: If battery status must to be charged after the communication between the inverter and battery is successful, it will show code 70 to charge battery. Not sure how to interpret that in English:) At some point I set the battery to user, but charging still didn't happen, so Thanks again for the response:) Added a data/config snapshot from SmartESS
  7. Hi BRG Thanks for the pointers. I can't recall powering off the inverter - will check out that behavior tomorrow. ATM busy charging via the Victron. Interestingly, connected to the Victron the generator output is very stable, drawing about 1.5KW. However, when I tried it on the Kodak the voltage would run up to 260V! Still maintaining bypass, but household loads were <500W at the time. The Kodak seems to really mess with the output regulation. It's a 5.5KVA diesel unit. I'll put a scope on it as well next time. Cheers
  8. Off grid. Only line in is the generator.
  9. Sure Charge source priority is Solar&Utility Output Source priority is Util Solar Bat That's where it is ATM, have tried various combos. Cheers
  10. Will do. Surely if the inverter syncs and goes into bypass, frequency shouldn't be the problem? As a quick fix before heading overseas, I've hooked up my old Victron Multiplus as a charger, which works perfectly. Sorts out the issue for now, but I need to get to the bottom of it and rely on the Kodak...
  11. Hi All Scratching my head here. I've just installed the above along with 2 Felicity 7.4kWh batteries, with BMS comms. No PV into the inverter, that's still handled by an existing Victron MPPT.(I need to rearrange the panels to up the voltage) When I connect the generator to the system the inverter the charging light doesn't come on, although it does sync. Every now and then the charge light flashes, but that's it. Never had an issue like this with other Voltronic inverters Any suggestions? I've tried all the combos I can think of. Cheers Ian

    Hi Ian, Are you considering selling the 16 cells and BMS referred to below? If so, your asking price? I am interested

    thanks, Racer

    Hi Roy I've upgraded from my old 120A - 16s2p DIY LBSA pack that has served me very well since 2020. 16 of the cells are going to family, but a full set of 16 and a Daly BT BMS will be available for sale. Ian

  14. Are you referring to the current displayed by the app? If so I have also noticed the fluctuations, which don't corresponding to the real values. Fortunately I don't reply on them. Cheers Ian
  15. Imtiaz, this reminds me of the situation my sister had after she bought a flat a few years back. The previous owner had been shocked in the shower, and the same happened 'randomly' to her after they moved in. Turns out that a shower cubicle mounting screw had penetrated the conduit to a downstairs guest toilet, energizing the whole unit if the light happened to be on. Nothing ever tripped, but water and electricity are great mates, and you don't need much to cause serious injury under those conditions. Bottom line, let your landlord know in writing, and let him know that you will be claiming in the event of injury. Should sharpen his focus, as it needs fixing ASAP
