Nice to be able to rely on the high quality components for peace of mind Can you give a breakdown of the solar panel costs?

If two batteries are connected in parallel, what would make one the "master"?

What would be meant by BMS' being "connected"? are we talking about some kind of direct ethernet/CANBUS communication? as far as I am aware, each battery has its own internal BMS

Howzit, potentially a stupid question be warned. Let's say you have a system all setup and running off of 1x 12V 100AH battery You run it for a few months, then decide, jirr, a second battery in parallel sounds lovely. Since battery A has already been used for a while, would there be a problem adding battery B because its at "100%" factory new while A may have declined ~90% for example? I'm struggling to understand under what scenario battery balancers / battery equalizers come into play EDIT: talking LifePO4 batteries with built in BMS

Thanks, Not too stressed about noise since I always wear headphones when my PC is on One thing I see about these Mecer inverters are that they are modified sine wave which might damage my PC over time? Thanks solid advice I didn't know about the efficiency drop-off with inverters. Could you advise which cable type/thickness I need to use to connect the S-120 to the VM1 Axpert? Since you work with these are you able to say if the charging settings can be configured to match the S-120? and can you set charge/discharge limits at 10% -> 90% to extend the overall lifespan?

My goal is to run my desktop PC during loadshedding (essentially a DIY UPS) I measured 300-400W load running various software Could I get some advice on the below config? battery (1.5 kWh) - https://www.sustainable.co.za/collections/lithium-batteries/products/hubble-s120-120ah-1-5kwh-12v-lithium-battery Inverter / Charger (1000W) - https://www.sustainable.co.za/collections/hybrid-inverters/products/rct-axpert-vm1-1k12-1kva-1kw-12v-hybrid-inverter Is this inverter/charger compatible with the chosen battery? Is this inverter/charger overkill for my goal? should I rather get an inverter and separate charger? Can I, in the future, drop in a second S120 battery in parallel to get 3kWh with this inverter? This UPS seems to be a cheaper option: https://www.geewiz.co.za/mecer-inverters/104647-mecer-1200va-720w-inverter-battery-charger-ups-intelligent-fan.html Appreciate any advice.

I want to run my desktop PC during loadshedding. I measured the power requirement to be 200-380W depending on load. I saw this system on takealot: https://www.takealot.com/ecoflow-river-pro-720wh-portable-power-station-black/PLID73199269 Seems to be exactly what I need. I'm not scared to DIY, my question is, is it possible to beat this pricing the DIY route? or is it probably a waste of effort.
