Recommendations for installer in Centurion


Recommended Posts

Hi all,

am planning a small system and require recommendations for an installer in Centurion.

 

I am thinking of installing the following  :

+- 3kVA Inverter (Victron or Goodwe or any equalivent capable of ESS type functionallity)

+- 3KWp of panels (e.g. 9x330W)

+- 3.5Kw worth of battery (e.g. 1xPylontech US3000)

Flat/tin roof, north facing

 

2 persons in a small 3 bedroom house - total monthly municipal account +- 600 units

To stay within recommended discharge current, you will need 2 pylontech batteries. you will have warranty issues if you dont follow that recommendation.

Can you please explain this?

A 3 kva unit at full load will draw 60 Amp from the Battery. The recommended discharge current for a 3.5kwh Pylon is 37 amps constant. At full load you will draw more than the recommended. I had a similar situation this week. I supplied a 5kva with only 3 pylons as the client plans to upgrade in the near future. The tech department of my supplier contacted me before releasing the equipment to inform me that I would void the Victron warranty if I dont connect the recommended 3 pylons capable of handling the full load demand from the inverter. The pylontach warranty will also be voided if you constantly discharge them at a rate higher than the recommended discharge current. 

I explained to the supplier that i have planned to limit the inverter power by way of settings ext, but they stuck to their guns and told me if something happens to the Unit because of the pylons switching off under load, that they will not honor the Warranty.

What inverter would you recommend to use with 2x 3.5kWh pylons.
