Hi!
I am new at this, but started investigating options to:
Keep basic functions (typically lights, microwave, fibre, laptops and TV) going during load shedding and:
Reduce electricity bill
The above is for a 3Ph residential setup. 3Ph is required fore some woodworking machines, etc. - which is not required to be functional during load shedding. Electricity usage average 30kWh/day. The intention is not to end up with an almost R0 electricity bill every month - rather to realise a substantial reduction. Metering is done with three x mechanical meters and reselling power to the municipality not a priority at this stage.
The intention is to opt for a 6 to 8 kW 3Ph hybrid inverter, a 3 to 5.5 kW lithium battery and 9 to 12 x (typically) 340W panels connected to one MPPT - leaving the option to add more panels to a second MPPT at a later stage. Whatever combination I end up with needs to be reliable but also affordable and I'd like to keep installation and operation as simple and uncluttered as possible.
Any comments on the above would be appreciated but most questions I have relates to the inverter itself:
What inverters could/should be considered (reliability & price)? Which ones should be avoided at all cost?
What options should I look for when shortlisting 3Ph hybrid inverters?
What else should be added to the basic list above (wiring excluded)?
Thanks in advance!
