I have a 5kw SNA Luxpower inverter, 3.61kw Greenrich lithium battery. System working 100%. My daily use is 150 to 300w. This usage is for fridges, lights, wifi's, tv's laptop, etc. We're also able to use washing machine, hair dyer for short periods, micro as well when needed. At 300w usage, and 4 hrs loadshedding, battery drops to 60% and recharges fully within 2 hrs. I want to add PV panels. Looking at 555w Jingo panel. Am I correct with the following calc?: 4 panels, 2.2kw at 70% should recharge battery battery in 2 hours from 60%, under good sunny conditions? Or should I add 2x555w, totalling 6 panels? Is this overkill? Regards Will

I have recently installed a Luxpower 5kw inverter with a Greenrich 3.6kw battery. It works 100%. The next step is to add solar panels to charge the battery, say within 2hrs, assuming its 95% depleted. Question is: what size and how many panels will do the job?

Thank you to those who responded! Fortunately I geld back on a final decision. Instead I Googled a lot, asked around, spoke to technicians, etc. And gained a lot of understanding as well as sorting out my current requirement and how it may change going forward. Currently I'm considering a solution, 5kw Luxpower(support in CT) and 3.5kw lithium battery. This fits my budget comfortably. Parallel operation supported(inverter and battery) and enough umph to add Panels later. Thanks to all and this Forum, who assisted to make an informed decision.

There are some many different inverters marketed today. It confuses me what to choose. I have 600 watt requirement. I'm being told that u need to triple it to have enough headroom. Is this correct ? Hence I'm looking at a 3Kw inverter, apparently 24V 200Ah lithium battery (hubble apparently best?) PV Input.? All these factors to consider vs Axpert Kodak, Voltron, kodak , mecer etc. The list goes on! Sunsynk is too expensive. How do you choose? The choice of Inverter is the problem. Pure sinewave? Parallel operation? Etc Help!!
