Pylontech Battery Inverter Compatibility – Victron, Deye, Solis, Growatt and SMA

Pylontech publishes compatibility lists identifying supported battery and inverter combinations.

However, brand-level compatibility is not model-level compatibility.

A Pylontech US5000, Fidus PRO and Force H3 must not be assumed compatible with the same inverters merely because they share the manufacturer’s name.

Professional buyers should confirm:

1. Exact battery and inverter models.
2. Low-voltage or high-voltage battery input architecture.
3. Battery operating voltage.
4. Charge and discharge limits.
5. CAN or RS485 communication protocol.
6. Communication cable pinout.
7. Firmware versions.
8. Approved battery expansion configuration.
9. Installation and commissioning settings.
10. Required backup and grid operating modes.

Pylontech Battery Expansion – Parallel Modules, BMS and LV Hub

Pylontech’s modular products support expansion only under their corresponding manufacturer instructions.

US5000 Expansion

The manufacturer specifies up to 16 US5000 modules in one approved parallel group.

For example:

• 2 US5000 modules = 9.6 kWh nominal capacity.
• 3 US5000 modules = 14.4 kWh.
• 4 US5000 modules = 19.2 kWh.
• 8 US5000 modules = 38.4 kWh.
• 16 US5000 modules = 76.8 kWh.

These figures show battery nominal capacity, not guaranteed inverter output power.

Fidus PRO Expansion

Pylontech’s Fidus system supports modular low-voltage expansion.

The manufacturer documentation distinguishes a single approved group from larger multi-group systems requiring a suitable LV Hub/controller architecture.

Large-scale expansion must not be implemented simply by joining unrestricted quantities of positive and negative DC terminals.

Before Adding Battery Modules

Installers should verify:

• Exact existing model and revision.
• Compatible replacement/expansion generation.
• Battery operating condition.
• Permitted group quantity.
• Required master module or controller.
• Power and communications cabling.
• Approved DC protection.
• SOC preparation and commissioning requirements.
• Battery firmware.
• Inverter current and capacity limits.

Pylontech Battery Storage Sizing – 5, 10, 15 and 20 kWh Systems

Residential battery sizing must consider evening consumption, available solar surplus, backup requirements and the inverter’s power limits.

The correct storage capacity is not determined simply by installing one kilowatt-hour of battery per kilowatt of solar panels.

Pylontech Battery Capacity Examples

These are additive module capacity calculations for suitable configurations. Actual energy delivered to AC loads will be lower after inverter losses and any additional operating reserves.

Example: Residential Evening Consumption of 9 kWh

Suppose a residential PV customer requires approximately 9 kWh of electricity overnight.

Two Pylontech US5000 modules provide 9.12 kWh of manufacturer-listed usable battery energy.

However, inverter conversion losses and backup SOC reserves can reduce the electricity actually available to household loads.

Therefore, two modules may be insufficient if the customer must receive a full 9 kWh at the AC output while also retaining a backup reserve.

A proper design should verify the actual consumption profile, usable SOC range, battery-to-load efficiency, inverter output power and available solar charging energy.

Pylontech Batteries for Off-Grid and Backup Power

Pylontech low-voltage battery systems can be suitable for selected off-grid and backup installations with approved inverter equipment.

Typical applications include:

• Off-grid homes.
• Remote properties.
• Agricultural facilities.
• Technical equipment backup.
• Hybrid PV installations with essential-load supply.
• Remote monitoring and communications infrastructure.

Battery Storage Does Not Automatically Provide Backup Power

A battery system connected to an ordinary grid-tie inverter does not necessarily provide power when the electricity grid fails.

Backup capability depends on the complete inverter or inverter/charger architecture, grid isolation provisions, control system and configured backup output.

Before selling a backup-ready system, the installer should check:

• Maximum backup output.
• Single-phase or three-phase architecture.
• Battery discharge power.
• Black-start requirements.
• Critical-load circuits.
• Grid-islanding functionality.
• Generator integration where relevant.
• Battery autonomy.
• Winter energy availability.
