EZA 100 and EZA 130

French company EZA is another major player in the off-grid, RV market. The 100 has prismatic Chinese cells, but they are assembled in Europe, and have a sturdy metal case compared to the plastic of all the others. The terminals are close together, and you would need to be careful with your spanner when connecting them. The unit has an internal BMS, and an array of LEDs on the top indicating state of charge.

Performance is close to its rated figure at 25A and 100A, but as it does not recommend being discharged at more then 100A we stopped here.

The EZA130 is a very substantial and sophisticated unit, again designed for the RV market, and assembled in France in a metal case. It has two inlet sockets and two outlets, and is designed to be connected to inputs from the engine alternator, plus an array of solar panels and a mains battery charger. The two outlets will supply normal 12V demands, plus an inverter. Inside it has an integral battery-to-battery charger, designed to be used with the latest vehicle smart alternators, and a solar controller. It has an automatic shut-off that disconnects the battery when not in use for long periods. Performance was up to its ratings at 25A and 130A, but again this was the maximum it was supposed to be discharged at.

Prices: £1,299 (EZA 100) and £2,995 (EZA 130).
