Keep our "Eskom" systems charged with solar?

[dunkyd]

Now that most of us are sitting with inverters and batteries which we all charge (hopefully?) once a month, what's the most economical way to keep the batteries charged via our free sun?

A small panel and a Steca controller ?

I have coupled to my inverter, 2 x 102 AH batteries, which I charge monthly with my inverter charger set to 10A. This takes maybe 8 to 10 hours and I thought I could trickle charge them constantly for a reasonable cost?

Any ideas out there ?

I don't think we'll have outages till next year if ever again seeings how many factories are closing.....

I have 4 x 105 a/h batteries, Inverter with built in 10A Charger, 2 x 300 watt Solar Panels, 40 amp Ecco Controller and my system stays connected 24/7 on a separate circuit.
At least once a week I run the system to 75% load for around 6 hours to drain the batteries a bit, to around 50%.
We have many mains breaks here also averaging about 1 - 10 hours at a time.
