One of the most reputable inverters on the market the Goodwe ES 4.5kW Hybrid inverter just does it all.
Ahead of its time, the Goodwe came on the market just as Hybrid inverters were becoming popular, with thousands of units sold every year and with little to no issues it's the SolarAdvice's go-to when suggesting an affordable, reliable and robust option.
What makes it so special?
The biggest advantages are the ability to have essential and non-essential loads , this enables you to add one essential load that consists of the lights, fridge and appliances you want as a first priority. The non-essential load can consist of bigger appliances such as washers, dryers, geysers or pumps for when you have excess power coming from the Solar array it can start powering those as a second priority. This is perfect for those wanting to run an energy sufficient household .
You also have 2 MPPT inputs that allow you to have 2 solar arrays independent from each other , this is especially good for sun coverage on roof structures that get different exposure strength during the day. Eliminating the inefficient panel issue you can have with the single string option.
Not only is the inverter fanless making it silent, but you can also install it outside undercover in a dry area out of the way.
Inverter Features
Essential & Non-Essential Loads

5-Year Warranty
Get peace of mind with a standard 5-year warranty with an option to extend to 10 years.
How Does The Hybrid Inverter Work?
The Hybrid inverter gives you the best of both worlds, not only does it act like a Grid-Tied inverter, but it also gives you the freedom of an Off-Grid inverter.
Often when wanting to go solar we think of "Off-Grid" and independence , but what if you can do that and fall back to the grid if for a period or even a moment you needed extra power? Then a Hybrid inverter is an ideal solution , you can have your cake and eat it too, plus it's cheaper!
Here are the different arrangements that you can have:
As you can see you can use this inverter as a UPS (Uninterrupted Power Supply) for when the grid goes down, or you can use it as Solar solution and you can use the backup system for night time use. Perfect for those looking to start with a backup in order to deal with Load Shedding, then upgrade to a Solar solution later by adding panels.
If you're looking for an automated solution that you will never need to manually intervene with, this is your perfect power companion .Goodwe ES Series Setup

I look at the GoodWe GW5048D-ES inverter the same way as I saw Nokia cell phones.
Both companies produce great hardware, but the operating software for both is poor.
In the case of GoodWe the operating firmware is not only poor, it is buggy too.
I have a GW5048D-ES and when grid power is lost during solar hours (think load shedding), the inverter barely charges the battery any more and discards many kW of potential pv generation when one needs the power the most.
This is extremely frustrating to witness.
During normal on grid operation the inverter MPPT system resets the opportaing point every time there is a load change in the household and then takes minutes to recover, consequently a large quantity of PV production is discarded every solar day. (Eg. If one has a stove plate running with a stew in a pot and the stove plate cycles on for a number of seconds and then remains off for some 10s of seconds on an ongoing cycle, the inverter exhibits very poor PV generation efficiency, again discaring kilowatts of potential PV generation.)
One can only hope that at some point GoodWe correct their poor firmware, which would then enable a good product.
Hi, thanks for your review on the Goodwe.
This has to be the first time we’ve had any issue with the Goodwe inverter, we would love to know more about the problem you’re having and perhaps your investigation will help us fix it for you.
Have you installed the app for the Goodwe? If so would you be able to share the data with us so we can check what’s happening?
And lastly what firmware version are you on?
Thanks!
Thanks for your interest in the issues I am having with this inverter. My installer tells me I am not the only GoodWe owner suffering with these issues. I am in direct contact with Mr D Havenga, and have supplied a number of reports to him, but I am becoming very frustrated with what seems to be an inability to correct the issues and an unwillingness to replace the inverter. I am running the very latest FW 181811. It is my opinion that 161608 was the least problematic on my system and every version there after (17178,171710,181810) has simply been worse.
Drop me a mail and we can chat and I’ll forward you my fault reports.
Hi
No problem, if you send your reports and everything else you have to [email protected] so we can assist you further.
So we have been running with this inverter for a while and we have to say we quite happy with. It can handle A LOT of concurrent load. For example in our case we were running 4 computers, 1 tv, a washing machine, and a kettle. . . . and this was working fine. We switched on the dishwasher which caused it to trip with so much load but it came back online within 5 mins by itself.
A note on the software. It’s very finicky to setup but once it works it gives you a lot of insight into what is happening with your usage and system. Great inverter overall
