Great battery - great value - love mine!

Hi, Does anybody have a view of what the standard lease / rental durations are of various Solar as a Service companies. I'm looking to lease a backup system for my tenant and looking for a term of ideally 12 months and max. 36 months. Versofy = 3 years GoSolr = ? Wetility = ? hohm energy = ? Stage Zero = ? Alumo = 3/5/7 year options available

ditto - where can one access this?

what is the passthrough capacity on the inverter - how much mains ac amps can you pass through to essentials on the 6kw and 8kw versions?

Hi - thank you indeed for the great review. Forgive me if it is implied, but can the Solis provide PV power (blended with mains and battery)to the non-essentials when grid is on? Like the Sunsynk can....I'd like to be sure I can use as much of the solar capacity as possible and the feature to use excess PV power on non-essentials is a great way to maximize the investment in panels....

Thanks for sharing! That's exactly what I'm hearing: "it can be done....but..." or "we just not used to doing it this way, but it should work..." Instead of using aux, would it be simpler to create an additional manual switch to move the non-essentials to essentials manually when there is enough solar for a temporary time while the grid is down. I know for average Joe this would not be …but for my scenario, in a small household where I can control and understand the parameters, I'd check that the solar output is more than enough and the activate whatever non-essential I'd need. After 1-2 hours, I'd then switch them off and move non-essentials back to essentials. I understand that if there is a sudden drop in solar, then the inverter would trip. But again, this is more for an emergency situation, say 3 day outage and you get desperate to use oven or get more hot water....

Thank you - noted! Needs to handle the peak....

Wanted: Inverter Trolley or Box Inverter Output 1000 - 1500 Watt Pure Sine Wave (to be used on fridge compressor) 2000Wh Lithium/LifePo Battery (e.g. +- 12v @ 200A or 24 v @ 100h) or similar in Durban (either for collection or with delivery). Should be Pure sine wave inverter to power fridge, TV, routers, cellphones, laptops etc. for 3-4 hours.

In principle agreed. Maybe I need to qualify this use case more: Put all non-essentials on Aux so that when needed, you can manually activate the Aux and manage the attached non-essentials to stay within the supply/load parameters. Imagine a 3-4 days outage (have had 2 of those this year). In such as scenario, I would love to go onto the app, activate the aux and manually load manage the non-essentials (example, if enough solar, then run the oven off solar, whilst checking that geyser is off and vice versa) - so it afford the opportunity of responsible use of the non-essentials with manual intervention which is better than not having them work at all when the grid is off and you have enough solar/battery at a given time...

I've read extensively about the Aux port on the Sunsynk and Deye inverters on this forum incl. the helpful PDF. Are there any downsides or limitations of using this port to connect to all NON-essentials? I am looking at getting a 5kw version and it seems that installers and SaaS providers are not keen to use the Aux port but the reason is unclear. Before anyone suggests to move all the NON-essentials to Essentials to keep it simple, please note this will not work for me. I need them split. However, esp. if we are going to stages 8-10 with >12 hours a day outages, it would be great to be able use NON-essentials on days when there is enough excess solar power on a sunny day (Esp. in a managed way). SO what are the downsides of making Aux = NON-Essentials? When the GRID is ON then I assume everything connected to the Aux port works exactly as if if it weren't on the Aux port as per traditional NON-essential setup? Is there any limitation in terms of amperage throughput or power "blending" of the different power sources to feed the load on Aux(i.e. the inverter sill uses solar, battery and AC grid power to service everything as optimally as possible)? Let's say I had a 5500W NON-Essential watt load running on the Aux with GRID ON. Would it simply use the AC passthrough or power from Grid to enable this? When the GRID is OFF, worst case scenario, Aux doesn't function as advertised OR you do not have enough solar/battery then all the NON-essentials are off and cannot be used anyway, just like when they are not connected to the Aux in the traditional case - no downside....I understand that you will still be limited during load shedding to the inverters rated output but if you have spare capacity within that limit you could use it..... I can't figure out why the default install method is not putting Non-Essentials on Aux.....

Yes - overall consumption is good. Was thinking the same - how to figure out what are my winter peaks? Is there anyway I can figure this out or measure it as layman - don't have much electrical / wiring knowledge....

Looking for someone who can propose and install a load shedding backup system. 2 person household, with a solar geyser currently installed (evacuated tubes with element as supplementary), total electricity usage in summer seems to be typically around 7-8 kwh per day and sometimes up to 11. Want to maximise the use of any solar energy that is created. Please message me if you are interested and have good credentials and references. Northern Suburbs, Jhb. Happy to get a good installer and source the components he specifies, if that helps or else turnkey.

I am trying to identify inverters that can do the following: I basically want to leverage excess solar power generation (when the grid is on) to power non-essentials like the geyser and some small underfloor heating (or even the oven). The Sunsynk solution uses the CT Coil to measure correctly and prevent feedback to the grid. The challenge I face, is that with my preferred installation setup, the CT coil cable length will end up being longer than the max. length specified (even when extended) and there is a space issue to get the CT clamp positioned around the incoming mains. Is there are alternative solution or other inverter brands, that does not require a CT clamp installed as per the Sunsynk method? Which inverter offers the same functionality (passthrough and blending on non-essentials without feedback to he grid) but without a CT coil required on the incoming mains? A friend has a Victron inverter and says his works fine like this but doesn't have the CT coil installed as per Sunsynk's way...
