Hi guys, what would you say are the best Inverter (no solar - yet, for later yes) of about 5KW right now... considering availability, cost and quality?

Thanks!

Totally depends on your budget

Depends a lot on budget. If you are serious about getting solar at a later stage I would look at a Sunsynk - they are getting really good reviews and are well supported. Sunsynk is not as good as a Victron but the pricing is a lot better.

If solar is not an option then a Mecer (Axpert) inverter will do the job. 

@CliveSAInteresting, why is Axpert not a candidate when you considering solar?

Check on availability. 

Just check if the axpert, like mecer has the floating bug issue. Mine does so the floating voltage needs to be set high which isn't great , else it never charges under over the floating voltage it seems and also the mecer axpert (not sure about others) doesn't seem to be able to take a battery past 50 percent whereas lithium battery can go to 30 percent discharge - meaning if you go lithium later you are giving away 20 percent usage for nothing.

I have an Axpert Mks4 5.6 and that issue is definitely not present, this is the first? time i'm hearing of it

I saw something about it on this forum - on the Mecer (3 and 5 KWs) ) , on some of the Mecers - but i definitely have it on mine, so maybe its not on all the axperts. 

 

glad you don't have it. can you set your axpert cutoff voltage lower than 50 percent though?

How are you setting a voltage value as a percentage?

Here's a screenshot from the watchtower app where I set the battery cutoff voltage. It's a voltage value, not a percentage

 

 

Maybe reference the exact post where you saw this behaviour?

It is a well know issue that has been around for years

Please show me where it's documented and discussed, I've never heard of it so I'm curious now

Hi @madness_za yes indeed its well known bug that has been addressed by @Coulomb, he has baked a solution into his patched firmwares that is widely used.

You can also get in touch with @Steve87 in order to gain insight and how  workarounds exist  for unpatched software.

 

Thanks Guys, I have decided to go with the Freedom Won Lite Home 10/8 and just need an appropriate 5KV inverter to suite that has no bugs in it that can be set to go to 70/80 percet of DOD and correct float voltage settings.
