Posted February 1, 20205 yr 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

I install in that area, I will be down there next week again for an installation. Pm me your details and Ill get into contact with you.

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.
February 2, 20205 yr Hi Jaco, So what is the recommended pylons for a Multiplus 11 48/5000? What the supplier said makes sense - but the costs will be crippling.

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