Max Power PV Tech 15000

Max Power PV Tech 15000 – 12kW Inverter with 15kW Solar Input

Max Power PV Tech 15000 is a higher-capacity inverter in the PV Tech product family. Its manufacturer-listed continuous AC output is 12kW / 12kVA, while the advertised maximum solar input is 15,000W. Do not treat the number 15000 in its model name as a 15kW continuous appliance rating. For offices, larger homes or shops, proper load and PV string design matters more than the model name.

Simple Q&A: 585W and 645W solar panels

How many 585W solar panels can this inverter support?

The inverter’s published PV power rating is 15,000W. On wattage alone, 25 × 585W equals 14,625W, while 26 equals 15,210W and goes above the stated limit. Therefore 25 modules is a preliminary maximum by power only. It is not a recommended wiring design, and 25 panels must not be connected all in series. An installer needs the module’s Vmp, Voc, temperature coefficient and current characteristics to select safe series and parallel strings.

What if I have LONGi or other 645W panels?

Twenty-three 645W panels total 14,835W. Twenty-four total 15,480W, above the stated 15,000W PV input power. Again, 23 is only wattage arithmetic: the actual usable number of strings and panels per string may be lower after considering the MPPT range, maximum open-circuit voltage, controller current rating and local minimum temperature. Different panel brands with the same 645W rating can have significantly different voltage/current.

Does the 60–450V MPPT range mean I can connect any number of panels?

No. MPPT range is a voltage operating window, not a panel-count instruction. Calculate each string’s Vmp at working temperature so it operates in the allowed range. Also calculate worst-case cold-weather open-circuit voltage. The inverter’s absolute maximum PV input voltage and PV input current must be read from its current datasheet before finalizing parallel strings. Do not assume values from a different PV Tech model.

Can the PV Tech 15000 run a 15kW AC load?

No. The manufacturer lists its continuous AC output at 12kW. The larger 15kW PV figure applies to DC solar-array input, not the AC output. Load planning must allow extra margin for refrigerators, pumps, compressors and air-conditioner starting current.

48V battery system questions

Can it work with lithium batteries?

Max Power lists lithium-ion and lead-acid battery compatibility with a 48V nominal system. Lithium BMS communication is not guaranteed for every battery brand: verify approved CAN/RS485 protocol, pinout and charger parameters against the exact battery and inverter revision. Do not connect a high-voltage battery stack to a 48V inverter.

How large a battery is needed?

Battery energy capacity depends on desired backup hours and average AC watts. For example, 3kW of average demand for two hours requires roughly 6kWh delivered energy before allowing for conversion losses and the battery’s usable discharge limits. A qualified designer should calculate practical usable storage rather than relying on inverter capacity alone.

Installation checks for a bigger system

At 12kW AC rating, the AC distribution board, grid connection, protective devices, neutral and earthing arrangements, PV DC isolation, lightning/surge protection and battery circuit all require professional engineering. Confirm inverter phase configuration, operating mode, local utility requirements and whether backup or grid-export functions are supported and approved. Keep ventilation and maintenance access according to the manufacturer’s manual.
