Usability
3.4 out of 10At 3,500 W continuous it sits on the 3,500 to 4,999 W rung for a 48 V all-in-one, so it scores 3 on capacity.
Renogy's manual rates inverter efficiency above 90 percent and idle draw at 48 W, which is 13.7 W per kW of its 3,500 W rating, both on the 4 rung, so it scores 4 on efficiency.
Its manual rates peak power at 7,000 VA, 2.0 times its continuous rating, so it scores 5 on operating range.
It switches over in 10 ms, carries the built-in MPPT controller and a 40 A AC charger equal to 160 A at 12 V, but its RS485/CAN port is documented only for Renogy's separate BT-2 Bluetooth module, with no stated battery BMS link, parallel stacking or 240 V output, so it scores 6 on features.
Renogy claims only CE and FCC marks for it, and no certifier directory searched (Intertek, UL Product iQ, CSA, the CEC list, LabTest, TÜV SÜD, TÜV Rheinland and SGS) lists the RIV4835CSH1S; Intertek holds records for its RIV4835PCS-1SS and RIV4836ECS-1SS siblings only, so it scores 2 on verification.

Older all-in-one, one-year warranty
The RIV4835CSH1S is Renogy's earlier 48 V solar inverter charger, a 3,500 W pure sine wave inverter with an 80 A MPPT controller and a 40 A AC charger for off-grid and backup systems.
It suits a buyer on a 48 V bank who wants solar, utility and generator charging with a 10 ms transfer in one box, and who will not need more than a year of warranty cover, closed-loop battery communication or 240 V output.

The Renogy RIV4835CSH1S is a 48 V all-in-one solar inverter charger: a 3,500 W (3,500 VA) pure sine wave inverter rated 7,000 VA peak, with an 80 A MPPT solar charge controller and a 40 A AC charger, by Renogy's manual and product page. Output is 120 VAC ±5 percent at 50 or 60 Hz, settable to 100, 105, 110 or 120 V with power derated in proportion. It runs from a 48 V battery between 40 and 60 V and starts at 44 V. The AC input takes 90 to 140 VAC with a 40 A bypass, and transfer takes 10 ms. The solar input has a 145 V recommended maximum open-circuit voltage (150 V actual), a 60 to 145 V operating range and a 60 to 115 V MPPT window at up to 50 A; the product page rates 4,400 W of PV input, the manual 4,800 W in and 4,500 W out. Solar and AC charging together reach 120 A. Renogy rates inverter efficiency above 90 percent, idle draw at 48 W and under 25 W in power-saver mode. It has an LCD with LED indicators, four charging modes (PV priority, utility priority, hybrid and solar only), three output modes, a dry-contact port, a wired-remote port and an RS485/CAN port that Renogy documents for its optional BT-2 Bluetooth module and DC Home app. It is fan-cooled, IP20 and rated 60 dB or less, and measures 426 x 322 x 124 mm (16.8 x 12.7 x 4.9 in) and weighs 23.8 lb. No battery cable is included; Renogy recommends 3 ft of 4 AWG. Renogy sells it alone at $769.99, with two 48V 50Ah batteries at $2,153.98 and with four at $3,477.98.
