  1. Hi Guys I have a friend who has had to abort installing a system in his home last minute. We need to sell the equipment sadly. We have the following: Victron Multiplus 2 48/5000/70-50 Cerbo GX Renusol Metal roof mounting system for 12 Panels MC's, cables etc 310watt ART Solar Panels 2x Hubble AM2 Batteries I am open to reasonable offers. Andrew 082 411 4060.
  2. Hi Guys I am a solar installer with a large client base in Johannesburg North. I’m looking for an electrician for the AC work. Please let me know if you are qualified and would like some work.
  3. Hi Guys I know City of Tswane and City of Cape Town are allowing SSEG's to feed electricity back into the grid and crediting various amounts per unit. Does anyone know of anywhere else in SA where this is allowed?
  4. Problem solved. The Dyness B4850 batteries I had didn't have dip switches, my supplier swopped them out for units with dip switches and now all is good. New problem I just encountered with a multiplus 2 gx is the local wifi connection has vanished and not returned after rebooting the venus and restarting and whole system. Anyone else had issues with Venus GX units?
  5. Hi Guys I can't get a Dyness B4850 battery to connect with my Victron Multiplus 2 GX. I have: Updated all Victron Firmware. Set the CAN-bus Profile - CAN-bus BMS (500 kbit/s) and used the Victron VE.Can to BMS CAN type B cable the right way around. Set DVCC on. Any ideas of where i'm going wrong?
  6. This makes a lot of sense. What happens when a Victron Multiplus 2 system has a full battery, PV Power available that are covering the AC loads and is in float? Does it ever bypass the battery?
  7. Hi Guys I am new to the forum and am sorry if this has already been discussed and made clear, but i haven't found anything on the forum or anywhere else that is 100% clear. I understand that we get 3 types of inverters, being: Offgrid: Unable to connect to the utility grid and back feed. No AC to DC charging. Able to charge DC to DC (solar to battery, MPPT included). Mostly for caravans etc, with no utility grid. Grid Tied: Able to connect to the utility grid and back feed. No AC to DC charging. Mostly for large PV systems without storage/backup. Hybrid: Able to connect to the utility grid and back feed. Able to charge from AC to DC. Able to charge DC to DC (solar to battery, MPPT included). For PV plus storage/backup systems. Is this correct? Whilst shopping around I noticed large price gaps in the same size inverters for two reasons: 1. Capacitor based vs Transformer based - big price gap. 2. Offgrid and Grid Tied, vs Hybrid - big price gap. I was satisfied with this until recently where I started looking at Hybrid Inverters like Goodwe and Sofar that are in my 'expensive' category but are capacitor based. So they are Hybrid.. yes, but my question is why is an Axpert not considered Hybrid if it seems to do everything? An Axpert Mark 2 and Growatt SPF TL HVM seem to do everything Hybrid Inverters do but are generally classified as Offgrid Inverters and are half the price. Is it because they cannot operate without batteries? Or can they not back feed into the utility grid? I am basically trying to understand what really classifies a Hybrid inverter and why they so much more expensive than offgrid inverters that have built in MPPT's and the ability to charge batteries from the grid?
