Description
The solar controller accepts up to 145–500 V from the panels depending on the version, so short strings are used with the smaller versions, while the larger ones allow long series chains of modules. The HVM variant delivers 230 V, and the LVM forms 120 V for equipment of the American standard. The 24 V bus is chosen for small systems and 48 V for more powerful ones, because at the same power the current in the battery cables is half as large. The transformerless design makes the enclosure light and suitable for wall mounting, but such an inverter handles motor inrush currents worse than transformer models. The efficiency reaches 93 %. Up to 6 units work in parallel, so the system power is increased gradually.
How to choose
First determine the continuous load power within 2000–5000 VA and the voltage of the existing or planned battery bank. The open-circuit voltage of the string must fit the MPPT limit of 145 to 500 V depending on the version. If you need more power in one unit or a large panel array, look at the SPF ES with 3500–6000 VA and up to 8000 W PV in the 6000 ES Plus. For pumps and compressors the SPF T with a low-frequency transformer of 3–18 kW is more suitable.

FAQ
What maximum panel voltage does the SPF TL accept?
The built-in MPPT controller accepts up to 145–500 V depending on the version. The open-circuit voltage of the string in frost is calculated with a margin below this limit.
Can a 24 V battery be connected to the SPF TL?
Yes, the inverter is available with a 24 V or 48 V battery bus, and the version is chosen for the existing battery bank.
How does the SPF TL HVM differ from the LVM?
The HVM delivers 230 V and the LVM 120 V. For networks and household appliances in Ukraine the HVM version is needed.
Can several SPF TL units be installed in parallel?
Yes, up to 6 units work in parallel and increase the total system power.
Is the SPF TL suitable for a country house without a grid?
Yes, an off-grid inverter of 2000–5000 VA with an MPPT controller, together with panels and a battery, forms a complete off-grid system with an efficiency of up to 93 %.
