Frequently Asked Questions
- The SAJ H2-12K-LT2 three phase hybrid inverter price in Pakistan is Rs 450,000 from MartOnline as of October 2026, including free delivery above Rs 50,000. It is the 12kW model of the SAJ H2 LT2 three phase series, which also includes the 16kW H2-16K-LT2 at Rs 545,000 and the 20kW H2-20K-LT2 at Rs 685,000. Contact MartOnline via WhatsApp at 0324-3493060 for the latest pricing.
- Yes. The SAJ H2-12K-LT2 is a three phase hybrid inverter and requires a three phase electricity connection from LESCO, K-Electric or your local DISCO. It outputs at 380/400V three phase and will not function on a single phase supply. To check your connection type, count the main live wires at your electricity meter — three live wires plus neutral confirms three phase. For single phase connections the SAJ H2 12kW single phase at Rs 365,000 is the correct alternative.
- The SAJ H2-12K-LT2 accepts a maximum PV array of 24,000Wp across 2 independent MPPTs, with a maximum DC input voltage of 1000V and an MPPT voltage range of 160V to 950V. At 200% DC oversizing, up to 40 panels of 600W connect across the two MPPT inputs. Each MPPT accepts up to 20A of input current with a maximum short circuit current of 25A per MPPT. This is confirmed in the official SAJ H2 LT2 datasheet V1.2-20250710.
- The SAJ H2-12K-LT2 accepts both LiFePO4 and lead-acid batteries in the 40V to 60V low voltage range via CAN or RS485 communication with self-adaption to BMS. It has dual battery inputs with a maximum charge and discharge current of 240A. Compatible batteries available from MartOnline include the SAJ 16kWh lithium battery at Rs 580,000, the Sunwoda Atrix Max+ 16kWh at Rs 600,000, and the Mesol 16kWh Infiniti at Rs 635,000.
- IP66 means the SAJ H2-12K-LT2 is completely dust-tight and protected against powerful water jets from any direction, as confirmed in the official SAJ H2 LT2 datasheet V1.2-20250710. This allows outdoor wall-mounted installation in sheltered locations without risk of dust or water ingress. The IP66 rating is particularly relevant for Pakistan where monsoon rain in Karachi from July to September and dusty conditions in Lahore during winter can affect inverters with lower protection ratings.
