Ahmed Naidoo –
The Dyness 5.12kWh battery is compact but punches well above its weight. Been cycling it daily since November and the capacity has not dropped at all. Pairs perfectly with my Deye inverter and setup was straightforward. Delivery to Durban North was two days ahead of schedule which was a nice bonus.
Liesel du Toit –
Excellent battery at a fair price. The build quality is impressive and the BMS handles everything automatically without needing to fiddle with settings. I can monitor the state of charge from my phone which gives real peace of mind during long outages. PowerVault was very helpful when I had questions before placing the order.
Shailen Pillay –
Bought two Dyness 5.12kWh batteries to pair with my Deye inverter in Durban and the system is working flawlessly. The BMS handles everything automatically and the batteries have been cycling daily for four months with no drop in performance. PowerVault offered the best price I found after checking five suppliers. Would definitely order from them again.
Monique Steenkamp –
Not many suppliers will deliver to Kimberley at a reasonable rate. PowerVault did, on time and well packed. The Dyness 5.12kWh battery has been pairing beautifully with my Sunsynk inverter. Five stars for the product and for the service. If you are in the Northern Cape and worried about getting support, do not be. Communication was excellent throughout.
