Assembling a bench ZYC SIMPO 5000 There’s no great mystery to it, but there are details that make the difference between a system that lasts ten years and one that starts playing up by the second winter. This is what the manufacturer’s manual says, organised in the way it’s done on site.
The SIMPO 5000 is IP20: It goes indoors, always. Site requirements:
Keep an eye on the weight: each module weighs 44 kg. A 10-unit cupboard with all its modules weighs over 450 kg. Check the floor structure before deciding where to place it.
The modules are designed for a 19-inch rack, 600 mm deep. ZYC offers two factory-pre-wired cabinets: the SIMPO Cabinet 6 (up to 6 modules, 30.7 kWh) and the SIMPO Cabinet 10 (up to 10.51.2 kWh). You can also mount the modules on a third-party rack or stack them with the SIMPO floor stand.
The cupboard is being wired up before to put it back in its place and before To fit the batteries: open the panels, connect the power terminals and the earth cable, and then move it into position.
The power cables to the inverter are not included. The cross-section depends on the system’s power rating:
| System power | 1 pair of cables | 2 pairs of cables |
| 10 kW | ≥ 70 mm² | ≥ 35 mm² |
| 20 kW | ≥ 120 mm² | ≥ 70 mm² |
| 30 kW | — | ≥ 95 mm² |
| 40 kW | — | ≥ 120 mm² |
| 50 kW | — | ≥ 150 mm² |
Terminals: SC xxx-12 for the 10- and SC xxx-10 for the 6, where “xxx” is the conductor section. And the other installation parameters:
| Fact | Value |
| Weight per module | 44 kg |
| Dimensions (W × H × D) | 482 × 134 × 518 mm (19″ rack format) |
| Required cupboard depth | 600 mm |
| Tightening torque for power cables — Cabinet 10 | 20 N·m |
| Tightening torque for power cables — Cabinet 6 | 15 N·m |
| Tightening torque for the earth cable | 5 N·m |
| Earth wire (PE) | ≥ 25 mm² with SC35-6 terminal |
| Communication cable | Shielded Cat5 or higher, max. 5 m |
| Degree of protection | IP20 (indoor installation) |
| Maximum altitude | 2,500 m |
Whether you’re setting up with no cupboard or with several cupboards side by side, there’s one rule you simply can’t break: All power cables must be the same length. If one module has a longer cable than another, its impedance is higher, it delivers less current and the array becomes unbalanced.
They are being installed from the bottom up, sliding them along the guides on each level. Two people per module: 44 kg is not something you can handle on your own, especially at chest height. Minimum equipment: safety footwear, insulated gloves, safety goggles, a torque wrench, a multimeter and a fire extinguisher to hand before you start.
When a wardrobe isn’t enough:
Manufacturer’s maximum: 80 modules in parallel on an inverter, and 64 when several cupboards are combined.
To switch it off, do the reverse: first the inverter, then the DC switch, then hold down the ON/OFF button on the master unit 3 seconds and check that the LEDs go out.
Important: If the system stops or loses its power supply, you must turn off the switch batteries. Leaving them connected whilst they slowly discharge is the most common way to ruin a new battery bank.
| LED | Status | What does it mean? |
| ALM | Power on | There is an error |
| ALM | Off | No errors |
| RUN | Permanent power supply | Working on communication with the investor |
| RUN | Slow flashing (1.5 s) | Working in offline mode |
| RUN | Off | The battery isn’t working |
| SOC | Number of lights on | Bench load level |
The SIMPO 5000 does not require frequent maintenance. An annual service is sufficient:
If the bank is going to be out of action for six months or more, you need to keep an eye on your blood pressure: if it’s above 51.6 V That’s fine, and it’s enough to check it every three months; if the voltage is lower than that, you’ll need to recharge it, otherwise the damage could be irreversible. The recommended recharge is at 55 V DC and a constant 10 A for around 30 minutes.
Load of -10 °C to +55 °C and download from -20 °C to +55 °C. That sub-zero discharge capacity is what sets this battery apart from most LFP batteries on the market, which stop working at 0 °C, and is why it is a sensible choice for shelters, unheated industrial buildings and pump houses.
