Frequently Asked Questions
Q: What does UL1741 Listed mean for my installation?
UL1741 is the US safety standard for grid-interconnected inverters. A UL1741 Listed inverter meets the electrical safety, grid-protection and anti-islanding requirements that US utilities and local inspectors recognize — which simplifies permit approval and utility interconnection for your solar + storage project.
Q: What is split-phase output and why does it matter?
Both models provide 120V on each leg (L1/N, L2/N) and 240V between legs (L1/L2), supporting common split-phase loads.
Q: Can the IP-Plus 12kW-P and 16kW-P be paralleled?
The series supports 1–6 units in parallel. Contact E-Able Power to discuss a configuration for your project.
Q: Which battery works with these inverters?
Both models use an external 51.2V battery bank (40–58.6Vdc range). Maximum AC/generator charge current is 160A for 12kW-P and 200A for 16kW-P; maximum PV charge current is 250A and 300A, respectively. The system supports lead-acid or lithium batteries.
Q: What monitoring and communication options are available?
The unit provides USB and RS485 interfaces with optional WiFi/GPRS for remote monitoring, plus dry-node control for generator or alarm signaling. The LCD panel shows system status, battery SOC and fault alarms, with power-saving mode below 25W per-phase load.
