Question 1

Which inverters work with the PB512100?

Accepted Answer

The PB512100 is a 51.2 V nominal pack, so it suits 48 V-class hybrid inverters and rack systems designed for 16-cell LiFePO₄. The charger should use a lithium profile matched to the label: 57.6 V max. charging voltage, 50 A max. charging current and 44.8 V cut-off voltage. Your Powrio dealer confirms settings during installation.

Question 2

How long will the PB512100 run my appliances?

Accepted Answer

As a rule of thumb, backup hours ≈ 5.12 kWh × 0.8 usable × 0.9 inverter efficiency ÷ your load in kW. At 1.5 kW that is about 2.5 hours. Real runtime depends on temperature and how your load varies.

Question 3

What warranty comes with the PB512100?

Accepted Answer

3–5 years, depending on the application. The exact term is printed on your digital warranty certificate, which you receive when you register the battery online.

Question 4

Can I check the PB512100's charge level?

Accepted Answer

Yes. The PB512100 has visual voltage and state-of-charge (SOC) monitoring on the unit, so you can see how much energy is left at a glance.

Question 5

How is the PB512100 protected?

Accepted Answer

With TriShield, the three protection layers printed on the label. The BMS is the software layer and protects against over-current, over-voltage, over-temperature and short circuit. The fuse and the MCB are independent hardware layers that protect against over-current and short circuit.

Question 6

Can I connect two PB512100 batteries in series or parallel?

Accepted Answer

No. The label on every Powrio pack says not to connect batteries in series or parallel. If you need more energy or power, choose a higher-capacity or higher-voltage model, or ask us about a custom pack.
