Best hybrid/solar solution

[MC-hammer]

Hey Guys

I'm thinking of adding a hybrid solar system, with battery backup to our home.

Does anyone have advice on what the best and most cost-effective solution for batteries, inverters ext to look out for?

Also, is Polytech batteries the best out there?
Are Sunsynk batteries good?

This all depends on your budget expected usage etc.

Gonna need to do initial research your side you essentially asked how long a piece of string is.

Hit up @DuracellBunny. He is an installer who also did my solar installation

Everything will be dependent on your budget available to spend.

100% the starting point.

Budget, then where or how can spend it.

Budget wise anything between 120k and 200k.

The place we moving to you has to pay R3k Eskom line rental since it's a small plot and don't see the point of paying Eskom 3k a month for line rental and then electricity usage on top of that when half the time we have load shedding. So might as well go full solar & perhaps a small wind generator

A friend of mine did an installation consisting of 6 x solar panels, 5.8kw Schubart inverter 5kw Akkutech battery for R70k but he has Eskom as a backup so runs intensive tasks on this. I know I would need something a bit more substantial for solar only.

What I would like to know is

1. Which brands are the best for batteries, inverters, and solar panels?
2. Which brands to stay away from?
3. What to look for when buying a battery and inverter?

Which one is best is somewhat subjective... it depends on the use cases but for Inverters the household names would be Victron, Sunsynk/Deye, Goodwe then evn some Voltronic clones (Axpert types do well for certain use cases ). Batteries would be Sunsynk, Pylontech, Dyness, FreedomWon, BYD and BSLBatt to name a few.

Look out for inverter + battery combos that can talk to each other (CAN or RS485 comms working 100%)

To go completely offgrid is quite a bit more expensive as you need to be able to carry yourself through a number of rainy/cloudy days. You can use a generator on those days but burning fuel is pricey.

In terms of brands plylon and sunsynk are good.

If you are fully off grid I would probably go for the cheaper axpert/voltronic inverters as you wont need blending or other features from a fancy hybrid inverter. (Kodak, Mecer as example brands)

Its hard to really recommend something without having all the information so people will likely just throw out a bunch of equipment they are familiar with if you dont get more detailed.
