Solar power system to run a fridge and few lights

[Eastboy 0]

Good Day

I have put together a few solar systems for a few lights and charging cellphones.

However I need to put a system together to run a fridge and a few lights for a few hours.

No idea where to start.

What solar panels to get, inverter needed, solar controller etc.

Any advice appreciated.

Howzit 

Start with power needed. 

Hours x watts ( 1 x Fridge 24hrs x 500w + lights 5 hrs x 10 leds x 5w etc) 

Peak power drawn (fridge +dishwasher +washing machine running simultaneously). This will determine Inverter. 

Determine day vs night usuage to indicate storage (battery size) 

Calculate daily usuage (utility bill / 30 days for estimate) this will indicate solar panels needed. 

Then speak to Steve from the @Powerforum Store for a good deal on  equipment. (I love my Sunsynk + Hubble combo) 

You can do the install yourself but still need to fork out R2000 for a COC. 

Speak to @leshenif you're not a DIY guy.

What is your objective? To provide backup power during power outages or are you moving towards a RE system to reduce your utility bill and become more independent of the grid? There's a big difference in every department between the two..

Good day.

You can look at a 24v 3Kw system. 

24V Pylontech battery with a 3Kw Synaps inverter. A complete pack would cost you about R22000.00, depending on the items you need for the system

Surely the pylontech 24v battery would almost cost that?

No they're about R17k nowadays.

Also consider the HOSELECT 24V battery if the Pylontech is too expensive. You may need a BMV/ICC though to determine state of charge. 900W of panels should be enough.

Hi everybody , I am new in this forum . Live in southern Chile.

@Eastboy : We have been living OffGrid for 1 1/2 years now and about electrical power the determining factor was "keep the fridge going"

Our equipment is : Voltronic Axpert VM 1000-12 Inverter ( has 40 A MPPT charger )  + 6 x 200 Watt 12 V solar panels + 2 x 170 Ah Narada AGM 12 V Batts

House (RV) ( Lights - water pump ) runs on 12 V Dc

Hope gives you an insigth.
