Reviews
Been using it nearly everyday for 6 months now on my high draw appliances, boiling jug, running induction hobs & airfrier.
Unit seems robust & well built. Remote display includes all the monitoring parameters.
Would be a bonus if it included 2x rubber gromets to replace the electrical glands when not hardwiring 240v outlets but found some without too much trouble for a few bucks. Excellent company to deal with.
We'd been looking for an 3KW inverter for our RV which has tons of solar and we'd also bought a 345Ah Battery from NZ Lithium. This fit the bill exactly wrt same company, capacity and recommendation. The team were really easy to contact and set things up with and the battery has arrived really quickly. Note: Haven't installed it yet.
